An improved method of preparing an aminoalkylalkoxy silane of the formula: ##STR1## in which R 1 and R 2 independently are alkyl groups having 1-8 carbon atoms, R 3 is a hydrogen atom or an alkyl group having 1-6 carbon atoms, R 4 and R 5 independently are a member selected from the group consisting of a hydrogen atom, an alkyl group having 1-10 carbon atoms, --CH 2 CH 2 NH 2 , --CH 2 CH 2 NHCH 2 CH 2 NH 2 , an allyl group, a substituted phenyl group and a nonsubstituted phenyl group and a is an integer from 0-2, comprises the step of reacting a silane compound with an allylamine in the presence of a catalyst composition selected from the group consisting of (1) a rhodium complex catalyst and a heterocyclic compound containing nitrogen and/or sulfur atoms and (2) a rhodium complex catalyst having a heterocyclic compound containing nitrogen and/or sulfur atoms as a ligand. |
