The tris silyl alkanes of formula (I), (II), (III) and (IV) are prepared by directly reacting a mixture of an organic compound of formula (V) having trichloromethyl gp., and a hydrogen chloride or its generating alkyl chloride of formula R'Cl with a silicon in the presence of copper catalyst at 200˜360 deg.C. The tris silyl alkanes of formula (I), (II), (III) and (IV) have each three dichlorosilyl gps., two dichlorosilyl gps. and one trichlorosilyl gp., one dichlorosilyl gp. and two trichlorosilyl gps., and three trichlorosilyl gps. In the formulas, R is H, methy; R1 is H, C1-4 alkyl or chloroethyl. The tris silyl alkanes is used as a starting material in the prodn. of a silicon compound having an organic functional gp.
