Title: Metal compound composition

Description:
BACKGROUND OF THE INVENTION  
       [0001] The present invention relates to a metal oxide and Lewis acid, for instance, carried on a polymer compound, which shows excellent solvent resistance, heat resistance, etc. and is not degraded in its activity even after repeating use.  
       [0002] It has heretofore been tried that metal oxides such as an osmium oxide which has high toxicity and is not easy to handle and a compound such as a Lewis acid having catalytic activity are made into micro-capsulated preparation with the use of an olefin type polymer such as polystyrene, whereby its handling becomes easy and its solvent resistance is increased (JACS 1998, 120, 2985; JOC 1998, 63, 6094; JACS 1999, 121, 11229). In those micro-capsulated metal oxides, repeating use becomes possible to some extent because of improvement of solvent resistance. However, the solvent resistance is not yet enough, and usable solvents and substrates have been restricted. Therefore, it has long been desired to provide catalytic active compositions such as metal oxides and Lewis acids whose solvent resistances are further increased.

     Experimental Example 1  
     [0123] To 9 mL of a solvent consisting of water-acetone-acetonitrile (1:1:1) were added 1 g of styrene, 1.5 g of N-methylmorpholine-N-oxide and 1.24 g of the metal oxide carried on the cross-linked polymer compound which was obtained in Example 2, followed by allowing a reaction to take place at room temperature for 5 hours with stirring. After the reaction, the metal oxide carried on the cross-linked polymer compound was recovered by filtration from the reaction solution, and the reaction solution was extracted with ethyl acetate and the organic layer was washed with water, concentrated and purified by column chromatography to give 1.2 g of 1-phenyl-1,2-ethanediol (yield: 86.2%).  
     [0124] Then, the recovered metal oxide carried on the cross-linked polymer compound was washed with methanol and a diol reaction of styrene was conducted after the same manner as above, and the metal oxide carried on the cross-linked polymer compound was again recovered. This step of processes was repeated several times.  
     [0125] Recovering rates in each step were shown in Table 2.

     [0126] Experimental Examples 2 and 3  
     [0127] A diol reaction of styrene was conducted after the same manner as in Experimental Example 1 except for using the metal oxides carried on the cross-linked polymer compound which were obtained in Example 3 and 4, respectively.  
     [0128] Yields of the diol in each step were also shown in Table 2.  
     [0129] As clear from the result in Experimental Examples 1 to 3, it was understood that the metal oxide carried on the cross-linked polymer compound of the present invention could be recovered quantitatively and the catalytic activity was not reduced even after repeating use.  
     [0130] The present invention provides a catalytic active substance such as a metal oxide and a Lewis acid having high solvent resistance and heat resistance, wherein no reduction of its activity is observed even after repeating use and which can easily be handled, and the metal oxide carried on a cross-linked polymer compound of the present invention can constantly express the activity of the carried metal oxide itself for a long period of time and additionally shows high durability and high solvent resistance, and therefore there is observed no reduction in its activity even after many times repeating use, and for this reason, the metal oxide is extraordinary useful as catalysts for various kinds of reactions.  
     [0131] Further, the present metal oxide can effectively be handled without taking care of toxicity, because it is carried on a cross-linked polymer compound, even if the metal oxide itself is not easily to handle from view point of its toxicity, etc.  
     [0132] The metal oxide carried on a cross-linked polymer compound of the present invention can be used industrially as catalysts for various kinds of reactions because of its excellent characteristics as mentioned above.
