Disclosed is a silyl thioalkene compound, as a class of organosilicon compounds, represented by the general formulaR(-CSAr=CHSiX3)n,in which the subscript n is 1 or 2, R is, when n is 1, a hydrogen atom or unsubstituted or substituted monovalent hydrocarbon group or, when n is 2, a divalent hydrocarbon group, Ar is an unsubstituted or nucleus-substituted aromatic monovalent aromatic hydrocarbon group and X is a halogen atom, a monovalent hydrocarbon group or hydrocarbyloxy group, having usefulness as an intermediate in the synthesis of various precision organic chemicals. The compound, of which X is a halogen atom X1, can be prepared, for example, by the reaction of an alkyne compound of the general formulaR(-C 3BOND CH)n,with a silyl sulfide compound of the general formulaArS-SiX13,in the presence of a platinum complex catalyst. The compound, of which X is a monovalent hydrocarbon group or a hydrocarbyloxy group, can be derived from the above obtained halogen-containing compound.
