    Abstract: PROBLEM TO BE SOLVED: To obtain the subject compound in high selectivity and in high yield under suppression of undesired side-reactions by adding a specific allyl compound to a specific silane in the presence of a specific catalyst under specific conditions. SOLUTION: The addition reaction of an allyl compound of the formula: H2C=CH-CH2X (X is Cl, Br, I or the like), for example, allyl chloride to a silane of the formula: R2R3R4SiH (R2-R4 are each H, a halogen, a 1-6C alkyl or the like) (preferably trichlorosilane) is carried out at 0-200 deg.C and at 200 millibar - 10 bar, preferably in the presence of a multielement catalyst supported on a carrier, for example, activated carbon, in which one of these elements is platinum, to give the objective three-functional compound (3- chloropropyltrichlorosilane). The other elements in the multielement catalyst are preferably Ti or the like and the molar ratios of the platinum to other elements on the carrier are preferably 0.05/1-20/1.
