OPTICAL BISSILYLATION REACTION OF UNSATURATED COMPOUND IN PRESENCE OF FULLERENE COMPOUNDS AS PHOTOSENSITIZER, ORGANIC SILICON COMPOUND OBTAINED BY THE REACTION

摘要

PROBLEM TO BE SOLVED: To obtain an organic silicon compound useful as an electric or electronic material, etc., by subjecting a specific disilylane and an unsaturated organic compound to a bissilylation reaction in the presence of a catalytic amount of a fullerene compound in a polar solvent under the irradiation of light having a specific wavelength. SOLUTION: A disilylane of formula I (R is a non-substituted or hydrocarbon group-substituted aryl group; X is an alkenyl group or 0) and an unsaturated organic compound of formula II (R1 is an aryl group or an alkyl group), etc., are subjected to a bissilylation reaction in a polar solvent containing a catalytic amount of a fullerene compound under the irradiation of light having a wavelength of >=400 nm to obtain the objective organic silicon compound of formula II, etc., comprising the addition product of the silicon compound of formula I to the unsaturated compound of formula II, The compound is especially useful for uses such as electric or electronic materials or raw materials for polymers.
