     DETAILED DESCRIPTION OF THE INVENTION 
     The compounds of Formula I exhibit geometrical and optical isomerism and may be prepared in geometrically or optically pure or mixed forms. The various individual optical and geometrical forms and various combinations thereof of the materials of the invention usually have some difference in herbicidal properties. Generally preferred for herbicidal efficacy are 1) those geometrical isomers of Formula I wherein the OW group resides on the same face of the carbocyclic ring as the O-Y bridge and 2) those optical isomers with the absolute configuration depicted in Formula Ia. The present invention contemplates all of the herbicidally active forms resulting from synthesis and from deliberately created mixtures. ##STR9## 
     The compounds of Formula Ia may be synthesized according to the well known Williamson Ether Synthesis (see N. Baggett in Comprehensive Organic Chemistry, D. Barton and W. D. Ollis eds., Vol. 1, pp. 819-832, Pergamon Press, New York (1979)) as shown in Scheme I by allowing bicyclic alcohols of Formula IV to react with appropriate alkylating agents represented as W-L where W represents those organic radicals defined previously and LG represents leaving group moieties such as chloride, bromide, iodide, and sulfonate esters. This is outlined in Scheme I. ##STR10## 
     The bicyclic alcohols of Formula IV are known in the art (U.S. Pat. Nos. 4,670,041; 4,529,806; 4,486,219) and the alkylating agents W-LG are prepared in the conventional manners known to those skilled in the art from the alcohols W-OH. 
     The alcohols, WOH, are generally known in the art and are most conveniently prepared through metal hydride (e.g., sodium borohydride) reduction of the corresponding bicyclic ketones which can be derived by Friedel-Crafts type cyclization of derivatives of phenylalkylcarboxylic acid, phenoxyalkylcarboxylic acids, phenylthioalkylcarboxylic acids, benzyloxyalkylcarboxylic acids, and benzylthioalkylcarboxylic acids. Details may be found in a) T. Laird in Comprehensive Organic Chemistry, D. Barton and W. D. Ollis, eds., Vol. 1, pp. 1165-1168, Pergamon Press, New York (1979); b) M. H. Palmer and N. M. Scollick, J. Chem. Soc., C., (1968), 2833; c) C. E. Dalgliesch and Mann, J. Chem. Soc., (1945), 893; d) C. D. Hurd and S. Hayao, J. Am. Chem. Soc., (1954), 76, 4299 and 5056; and e) R. Lesser, Chem. Ber., (1923), 56, 1642. 
     Alternatively, the compounds of Formula Ia may be prepared by the coupling procedure described in Scheme II, which is used in cases where the standard Williamson ether synthesis proves problematic. This procedure uses a Lewis acidic metal oxide wherein the metal can remove the halide ion by forming an insoluble precipitate. In Example 1, silver (I) oxide is used and the silver halide is the co-product. Alternative metal oxides that may be used are HgO, CaO, MgO. N,N-Dimethylformamide and ethereal solvents, such as diethyl ether, tetrahydrofuran, dioxane, or 1,2-dimethoxyethane are the preferred solvents. Other solvents likely to provide good yields include dipolar aprotic solvents like dimethyl sulfoxide, acetone and N,N&#39;-dimethylpropyleneurea. ##STR11## 
     The synthetic procedure shown in Scheme III may be used to prepare compounds of Formula Ia wherein Z 1  is a heteroatom (such as N, O, S). The coupling substrate is a styrene with an appropriate substituted heteroatom in protected form (such as with a trialkylsilyl, acetate ester, benzoate ester, etc.). A mild halogenating agent such as N-halosuccinimide, N-haloacetamide, dioxane dihalide, or pyridinium hydrohalide perhalide may be used to form a cyclic halonium ion under optional acid catalysis. The ion is intercepted at the benzylic center to form the benzylic ether. The heteroatom is deprotected and allowed to close in situ to form the desired heterocyclic ring. The acid catalyst for the initial coupling can be used in either concentrated or diluted form. ##STR12## 
    
    
     EXAMPLE 1 
     (±)-exo-2-(2,3-Dihydro-1H-inden-2-yl-oxy)-1-methyl-4-(1-methylethyl)-7-Oxabicyclo[2.2.1]heptane 
     (±)-Exo-1-methyl-4-(1-methylethyl)-7-oxabicyclo[2.2.1]heptane-2-ol (2.51 g, 14.7 mmoles) was dissolved in 7.3 mL of diethyl ether in a one-neck flask. 1-chloroindane (3.37 g, 22.1 mmoles) was then added, followed by silver (I) oxide (Aldrich, 3.41 g, 16.2 mmoles). A reflux condenser was fitted to the flask and the reaction was heated at reflux for 12 hrs. The mixture was allowed to cool and filtered through a pad of Celite Florisil or SiO 2 . The filter cake was washed with diethyl ether, the filtrate was concentrated and chromatographed on SiO 2  (10-20% Et 2  O/hexane) to obtain 2.12 g (51%) of the desired product as an oil in a 1:1 mixture of diastereomers. 
       1  H-NMR (CDCl 3 , 200 MHz): 7.40 (m, 1H); 7.23 (m, 3H); 4.95 (app.t, 1H); 3.75 (m, 1H); 3.10 (m, 1H); 2.80 (m, 1H); 2.50-2.00 (m, 4H); 2.80-2.40 (m, 8H); 1.05 (2d, 6H). 
     EXAMPLE 2 
     Exo-2-[2,3-dihydrobenzofuran-3-yl-oxy]-1-methyl-4-(1-methylethyl)-7-oxabicyclo[2.2.1]heptane 
     2-ethenyl phenol was synthesized according to the procedure of Corson et al. (J. Org. Chem., 1958, 23, 544) and silated by standard procedures. 2-t-butyldimethylsiloxy styrene (550 mg, 2.03 mmoles) was dissolved in tetrahydrofuran (4.0 mL). Exo-1-methyl-4-(1-methylethyl)-7-oxabicyclo[2.2.1]heptane-2-ol (690 mg, 4.06 mmoles) and N-bromosuccinimide were added. One drop of perchloric acid (70%) was added. The reaction was stirred for 11/2 hrs after which time a 1M solution of tetrabutylammonium fluoride in THF (2.5 mL) (any fluoride source, such as KF, NaF, CaF 2 , HF will suffice) was added and the solution was stirred for an hour. The reaction mixture was diluted with diethyl ether and washed with H 2  O. The organic layer was dried over anhydrous Na 2  SO 4 , filtered, and concentrated. It was then chromatographed on SiO 2  (10-20% Et 2  O/hexane) to obtain 210 mg of the desired product in about 95% purity. 
       1  H-NMR (CDCl 3 , 200 MHz): 7.30 (m, 1H); 7.25 (app. tdd, 1H); 6.90 (m, 2H); 5.10 (td, 1H); 4.85 (m, 2H); 3.70 (2dd, 1H); 2.15-1.90 (m, 2H); 1.70-1.30 (m, 8H); 0.98 (2d, 6H). 
     By the general procedures described, or by obvious modifications thereof, the compounds of Tables 1 to 8 can be prepared.

     FORMULATIONS 
     Useful formulations of the compounds of Formula I can be prepared in conventional ways. They include dusts, granules, pellets, solutions, suspensions, emulsions, wettable powders, emulsifiable concentrates and the like. Many of these may be applied directly. Sprayable formulations can be extended in suitable media and used at spray volumes of from a few liters to several hundred liters per hectare. High strength compositions are primarily used as intermediates for further formulation. The formulations, broadly, contain about 0.1% to 99% by weight of active ingredient(s) and at least one of (a) about 0.1% to 20% surfactant(s) and (b) about 1% to 99.9% solid or liquid diluent(s). More specifically, they will contain these ingredients in the following approximate proportions: 
     
                       TABLE 9______________________________________       Active  Weight Percent*       Ingredient               Diluent(s)                         Surfactant(s)______________________________________Wettable Powders         5-60      39-94     1-10Emulsifiable  3-80      20-95     0-20ConcentratesDusts         1-25      70-99     0-5Granules and Pellets         0.1-50      50-99.9 0-15______________________________________ *Active ingredient plus at least one of a Surfactant or a Diluent equals 100 weight percent. 
    
     Lower or higher levels of active ingredient can, of course, be present depending on the intended use and the physical properties of the compound. Higher ratios of surfactant to active ingredient are sometimes desirable, and are achieved by incorporation into the formulation or by tank mixing. 
     Typical solid diluents are described in Watkins, et al., &#34;Handbook of Insecticide Dust Diluents and Carriers&#34;, 2nd Ed., Dorland Books, Caldwell, N.J., but other solids, either mined or manufactured, may be used. The more absorptive diluents are preferred for wettable powders and the denser ones for dusts. Typical liquid diluents and solvents are described in Marsden, &#34;Solvents Guide,&#34; 2nd Ed., Interscience, New York, 1950. Solubility under 0.1% is preferred for suspension concentrates; solution concentrates are preferably stable against phase separation at 0° C. &#34;McCutcheon&#39;s Detergents and Emulsifiers Annual&#34;, MC Publishing Corp., Ridgewood, N.J., as well as Sisely and Wood, &#34;Encyclopedia of Surface Active Agents&#34;, Chemical Publishing Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foaming, caking, corrosion, microbiological growth, etc. 
     The methods of making such compositions are well known. Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending and, usually, grinding as in a hammer or fluid energy mill. Suspensions are prepared by wet milling (see, for example, Littler, U.S. Pat. No. 3,060,084). Granules and pellets may be made by spraying the active material upon preformed granular carriers or by agglomeration techniques. See J. E. Browning, &#34;Agglomeration&#34;, Chemical Engineering, Dec. 4, 1967, pp. 147ff. and &#34;Perry&#39;s Chemical Engineer&#39;s Handbook&#34;, 5th Ed., McGraw-Hill, New York, 1973, pp. 8-57ff.

     UTILITY 
     Test results indicate that compounds of this invention are highly active preemergent and/or postemergent herbicides or plant growth regulants. These compounds are useful for postemergence grass control in agronomic crops and are particularly useful for preemergence broad-spectrum grass and selected small-seeded broadleaf weed control in agronomic crops. Agronomic crops such as barley (Hordeum vulgare), corn (Zea mays), cotton (Gossypium hirsutum), rape (Brassica napus), rice (Oryza sativa), sorghum (Sorghum bicolor), soybean (Glycine max), sugar beet (Beta vulgaris), and wheat (Triticum aestivum) show little or no injury when treated with application rates necessary for weed control for many of the compounds in this invention. Many of the compounds of this invention are also particularly suitable for barnyardgrass (Echinochloa crus-galli) control in transplanted rice. Troublesome weed species that are suppressed or controlled are grass weeds such as barnyardgrass (Echinochloa crus-galli), blackgrass (Alopecurus myosuroides), cheatgrass (Bromus secalinus), crabgrass (Digitaria spp.), downy brome (Bromus tectorum), foxtail (Setaria spp.), johnsongrass (Sorghum halepense), and wild oat (Avena fatua); broadleaf weeds such as lambsquarters (Chenopodium album) and velvetleaf (Abutilon theophrasti); and sedge (Cyperus spp.). 
     Test results also indicate that compounds of this invention have utility for broad-spectrum pre-and/or postemergence weed control in other areas where control of vegetation is desired, such as around storage tanks, parking lots, drive-in theaters, billboards, highways, and railroad structures and in fallow areas of crop production such as in wheat, barley, and in plantation crops such as palm, pineapple, plantin, banana, citrus, rubber, sugarcane, etc. 
     Rates of application for compounds of this invention are determined by a number of factors. These factors include: formulation selected, method of application, amount of vegetation present, growing conditions, etc. In general terms, the subject compounds should be applied at rates from 0.01 to 20 kg/ha with a preferred rate range of from 0.05 to 1 kg/ha. One skilled in the art can easily determine rates needed for the desired level of weed control. 
     Compounds of this invention may be used alone or in combination with other commercial herbicides, insecticides, or fungicides. The following list exemplifies some of the herbicides suitable for use in mixtures. A combination of a compound from this invention with one or more of the following herbicides may be particularly useful for weed control.

     TEST A 
     Seeds of barley (Hordeum vulgare), barnyardgrass (Echinochloa crus-galli), cheatgrass (Bromus secalinus), cocklebur (Xanthium pensylvanicum), corn (Zea mays), cotton (Gossypium hirsutum), crabgrass (Digitaria spp.), giant foxtail (Setaria faberi), morningglory (Ipomoea spp.), rice (Oryza sativa), sorghum (Sorghum bicolor), soybean (Glycine max), sugar beet (Beta vulgaris), velvetleaf (Abutilon theophrasti), wheat (Triticum aestivum), and wild oat (Avena fatua) and purple nutsedge (Cyperus rotundus) tubers were planted and treated preemergence with test chemicals dissolved in a non-phytotoxic solvent. At the same time, these crop and weed species were also treated with postemergence applications of test chemicals. Plants ranged in height from two to eighteen cm (two to three leaf stage) for postemergence treatments. Treated plants and controls were maintained in a greenhouse for approximately sixteen days, after which all species were compared to controls and visually evaluated. Plant response ratings, summarized in Table A, are based on a scale of 0 to 10 where 0 is no effect and 10 is complete control. A dash (-) response means no test result. The accompanying descriptive symbols have the following meanings: 
     B=burn injury; 
     C=chlorosis/necrosis; 
     E=inhibition of emergence; 
     G=growth retardation; 
     H=formative effect; 
     P=terminal bud injury; and 
     S=albinism.

     Seeds of barley (Hordeum vulgare), barnyardgrass (Echinochloa crus-galli), blackgrass (Alopecurus myosuroides), chickweed (Stellaria media), cocklebur (Xanthium pensylvanicum), corn (Zea mays), cotton (Gossypium hirsutum), crabgrass (Digitaria spp.), downy brome (Bromus tectorum), giant foxtail (Setaria faberi), green foxtail (Setaria viridis), jimsonweed (Datura stramonium), johnsongrass (Sorghum halepense), lambsquarters (Chenopodium album), morningglory (Ipomoea spp.), rape (Brassica napus), rice (Oryza sativa), sicklepod (Cassia obtusifolia), soybean (Glycine max), sugar beet (Beta vulgaris), teaweed (Sida spinosa), velvetleaf (Abutilon theophrasti), wheat (Triticum aestivum), wild buckwheat (Polygonum convolvulus), and wild oat (Avena fatua) and purple nutsedge (Cyperus rotundus) tubers were planted and treated preemergence with test chemicals dissolved in a non-phytotoxic solvent. At the same time, these crop and weed species were also treated with postemergence applications of test chemicals. Plants ranged in height from two to eighteen cm (two to three leaf stage) for postemergence treatments. Treated plants and controls were maintained in a greenhouse for approximately 24 days, after which all species were compared to controls and visually evaluated. Preemergence and postemergence application rates for each compound are listed in Table B. Plant response ratings, summarized in Table B, are based on a scale of 0 to 100 where 0 is no effect and 100 is complete control. A dash (-) response means no test result.

     TEST C 
     Plastic pots were partially filled with silt loam soil. The soil was then saturated with water. Indica and Japonica rice (Oryza sativa) seedlings at the 2.0 to 2.5 leaf stage, seeds of barnyardgrass (Echinochloa crus-galli), bulrush (Scirpus mucronatus), and umbrella sedge (Cyperus difformis), and sprouted tubers of arrowhead (Sagittaria spp). and waterchestnut (Eleocharis spp.) were planted into this soil. Several days after planting, water levels were raised to 3 cm above the soil surface and maintained at this level throughout the test. Chemical treatments were formulated in a non-phytotoxic solvent and applied directly to the paddy water. Treated plants and controls were maintained in a greenhouse for approximately 21 days, after which all species were compared to controls and visually evaluated. Plant response ratings, summarized in Table C, are based on a scale of 0 to 100 where 0 is no effect and 100 is complete control. A dash (-) response means no test result.

     Seeds of spring and winter barley (Hordeum vulgare), black nightshade (Solanum nigrum), blackgrass (Alopercurus myosuroides), bluegrass (Poa annua), catchweed bedstraw (Gallium aparine), cheatgrass (Bromus secalinus), downy brome (Bromus tectorum), field pennycress (Thlaspi arvense), field violet (Viola arvensis), green foxtail (Setaria viridis), Italian ryegrass (Lolium multiflorum), ivyleaf speedwell (Veronica hederaefolia), jointed goatgrass (Aegilops cylindrica), kochia (Kochia scoparia), lambsquarters (Chenopodium album), Persian speedwell (Veronica persica), rape (Brassica napus), Russian thistle (Salsola kali), scentless chamomile (Matricaria inodora), sugar beet (Beta vulgaris), spring and winter wheat (Triticum aestivum), wild buckwheat (Polygonum convolvulus), and wild oat (Avena fatua) were planted and treated preemergence with test chemicals dissolved in a non-phytotoxic solvent. Postemergence applications of test chemicals were also applied to these same crop and weed species. Plants ranged in height from two to twenty-four cm (two to three leaf stage) for postemergence treatments. Blackgrass and wild oat were treated postemergence at two growth stages--the first stage being at two to three leaves and the second stage being approximately at four leaves or in the initial stages of tillering. Treated plants and controls were maintained in a greenhouse for approximately 21 days, after which all species were compared to controls and visually evaluated. Rates of application of each compound are listed in Table D. Plant response ratings, summarized in Table D, are based on a scale of 0 to 100 where 0 is no effect and 100 is complete control.
