する場合が一般的に収率が高い。The reaction between the unsaturated epoxy compound and the organotin compound described above can be carried out by bringing them into contact in the presence of boron trifluoride, boron trifluoride etherate (e.g. diethyl niteller) or aluminum chloride as a catalyst. However, from the viewpoint of reaction selectivity, the reaction temperature is preferably relatively low, such as 0 to -80°C. Although the reaction solvent is not essential, it is preferable to use one that does not participate in the reaction from the viewpoint of selectivity; for example, methylene chloride, carbon tetrachloride, chloroform, etc. can be used. General formula (III
) The ratio of the unsaturated epoxy compound represented by formula (IV) to the organotin compound represented by general formula (IV) is not strict, but
A suitable range is 0.2 to 5 moles of the latter per 1 mole of the former. The order of charging the reactants and catalyst can be arbitrarily selected, but for example, in a reaction using boron trifluoride etherate as a catalyst, an unsaturated epoxy compound represented by the general formula (I[I) and the general formula (F/) The yield is generally high when boron trisulfide etherate is added dropwise to a mixed solution with the organotin compound represented by:
