    Abstract: PROBLEM TO BE SOLVED: To obtain a novel compound bearing a tri-substituted silyl-aliphatic group that bonds to platinum with a carbon-platinum bond, which is useful for curing an irradiation-curable silicone composition to which the addition reaction between a silicon-bonding hydride and an aliphatic unsaturated group- containing substance participates. SOLUTION: This novel compound is an optically active cyclo-pentadienyl platinum (IV) compound bearing a tri-substituted silylaliphatic group that is boned to platinum via a carbon-platinum bond, typically [1-methyl-3-(9'- phenanthrylmethyl)cyclopentadienyl] dimethyltrimethylsilylmethylplatinum. This exemplified compound is prepared by allowing a compound of formula I: Pt (CH3)2CH2Si(CH3)3 to react with lithium 1-methyl-3-(9'-phenanthril)- cyclopentadienide.
