Title: Improvements in or relating to organo-mercury compounds
IPC: C07F3/10
Filed: 1962-02-22
Abstract: The invention comprises organo-mercury compounds of formula <FORM:0974709/C1/1> wherein X represents a halogen atom (preferably chlorine or bromine) R1 represents a C1-C5 alkyl group, and <FORM:0974709/C1/2> represents a cyclic group containing twelve carbon atoms which may have a double bond, an epoxide group or two vicinal hydroxy groups in either or both of the 5,6- and 9,10-positions. Compounds specified are 1-halogenomercuri-2-alkoxycyclododecadi-5, 9-enes (from trans-trans-trans and trans-trans-cis-cyclo-dodecatri-1, 5,9-enes), 1-halogenomercuri -2- alkoxycyclododecanes (from cyclododecene), 1,2-epoxy-5 (or 6)-halogenomercuri-6 (or 5)-alkoxycyclododec -9- enes (from 1, 2-epoxy-cyclodedecadi-5, 9-ene) and 5 (or 6)- halogenomercuri-6 (or 5)-alkoxycyclododec -9- en-1, 2-diols from cyclododecadi-5,9-en-1,2-diol). They may be prepared by reacting in the presence of an aliphatic alcohol R1OH (where R1 is C1-C5 alkyl) an ethylenically unsaturated cyclic compound of formula <FORM:0974709/C1/3> the grouping <FORM:0974709/C1/4> being as above defined, with a mercuric salt of a carboxylic acid, treating the acyloxy mercuric compound thus obtained with an alkali metal halide, and separating the resultant organo-mercury compound from the reaction mixture. The reaction with the mercuric carboxylic is preferably carried out at room temperature, and that with the alkali metal halide at a temperature below 10 DEG C.  The compounds of the invention possess fungicidal activity (see Divisions A5, C4 and D2).ALSO:A fungicidal compound for addition to paint comprises an organo mercury compound of formula <FORM:0974709/C4-C5/1> wherein X represents a halogen atom (preferably chlorine or bromine), R1 represents a C1-C5 alkyl group, and <FORM:0974709/C4-C5/2> represents a cyclic group containing twelve carbon atoms which may have a double bond, an epoxide group or two vicinal hydroxy groups in either or both of the 5,6- and 9,10-positions. Specified compounds include 1-halogeno-mercuri - 2 - alkoxycyclododecadi - 5,9 - enes, 1 - halogenomercuri - 2 - alkoxycyclododecanes, 1,2 - epoxy - 5(or 6) - halogenomercuri - 6(or 5)-alkoxycyclododec - 9 - enes and 5(or 6) - halogenomercuri - 6(or 5) - alkoxycyclododec - 9 - en-1,2-diols.ALSO:A fungicidal composition for the treatment of plants and seeds comprises an organo mercury compound of formula <FORM:0974709/A5-A6/1> wherein X represents a halogen atom (preferably chlorine or bromine), R1 represents a C1-C5 alkyl group, and <FORM:0974709/A5-A6/2> represents a cyclic group containing twelve carbon atoms which may have a double bond, an epoxide group or two vicinal hydroxy groups in either or both of the 5,6- and 9,10-positions.  Specified compounds include 1-halogenomercuri-2 - alkoxycyclododecadi - 5,9 - enes, 1 - halogenomercuri - 2 - alkoxycyclododecanes, 1,2-epoxy - 5- (or 6)-halogenomercuri-6- (or 5)-alkoxycyclododec-9-enes and 5- (or 6)-halogenomercuri-6- (or 5)-alkoxycyclododec-9-en-1,2-diols.  The compound may be mixed with a diluent or carrier such as talc, calcined magnesia, kieselguhr, tricalcium phosphate, powdered cork, absorbent carbon black or a clay such as kaolin or bentonite; or formulated as an aerosol, suspension, emulsion or solution in water or organic media such as toluene, xylene, mineral, animal or vegetable oils or mixtures of these diluents.  Liquid compositions may contain ionic or non-ionic wetting agents such as sulphoricinoleates, quaternary ammonium derivatives, condensates of ethylene oxide with octyl phenol or fatty acid esters of anhydrosorbitols rendered soluble by etherification of the free hydroxyl groups with ethylene oxide (see Examples VIII and IX).ALSO:A fungicidal compound for addition to paper pulp comprises an organo mercury compound of formula <FORM:0974709/D1-D2/1> wherein X represents a halogen atom (preferably chlorine or bromine), R1 represents a C1-C5 alkyl group, and <FORM:0974709/D1-D2/2> represents a cyclic group containing twelve carbon atoms which may have a double bond, an epoxide group or two vicinal hydroxy groups in either or both of the 5, 6-and 9, 10-positions.  Specified compounds include 1-halogenomercuri-2-alkoxycyclododecadi-5, 9-enes, 1-halogenomercuri-2-alkoxycyclododecanes, 1, 2-epoxy-5(or 6)-halogenomercuri-6(or 5)-alkoxycyclododec-9-enes and 5(or 6)-halogenomercuri-6(or 5)-alkoxycyclododec-9-en-1, 2-diols.
