The present invention relates to a process for preparing organosilicon compounds by the silylation of conjugated dienes and more particularly, to the process for preparing organosilicon compounds expressed by the following Formulas 1a and 1b in high yield, comprising the steps of heating trichlorosilane in the presence of quaternary organophosphonium salt catalyst to generate dichlorosilylene (:SiCl2); and silylating the result with linear or cyclic conjugated dienes, wherein R1, R2, R3, R4, R5 and R6 are independently a hydrogen atom, a C1-C6 alkyl, phenyl group, or two functional groups among R1, R2, R3, R4, R5 and R6 may be covalently bonded to each other to form a cyclic compound of C4-C8.
