Abstract
An improved method of preparing an aminoalkylalkoxy silane of the formula: ##STR1## in which R.sup.1 and R.sup.2 independently are alkyl groups having 1-8 carbon atoms, R.sup.3 is a hydrogen atom or an alkyl group having 1-6 carbon atoms, R.sup.4 and R.sup.5 independently are a member selected from the group consisting of a hydrogen atom, an alkyl group having 1-10 carbon atoms, --CH.sub.2 CH.sub.2 NH.sub.2, --CH.sub.2 CH.sub.2 NHCH.sub.2 CH.sub.2 NH.sub.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.
