Claim:
A method for preparing aminoorganyltriorganylsilanes of the formula (1) R′ 3-n R 1 n Si—R 2 —NR 3 R 4 (1), comprising reacting cyclic or acyclic amines of the formula (2), H—NR 3 R 4 (2), with (haloorganyl)silanes of the formula (3) R′ 3-n —R 1 n Si—R 2 —X (3), in which R′ is a C 1-10 acyloxy radical or C 1-10 alkoxy radical, R 1 is a C 1-10 hydrocarbon radical, R 2 is a C 1-10 divalent hydrocarbon radical, R 3 , R 4 , independently of one another, are hydrogen or a C 1-10 hydrocarbon radical, wherein R 3 and R 4 are optionally linked to one another to form a ring structure, the ring structure optionally containing heteroatoms, n is 0, 1, 2 or 3, and X is chlorine, bromine or iodine, the step of reacting comprising the following steps: a) reacting the (haloorganyl)silane of the formula (3) and the amine of the formula (2) at a temperature of from 0 to 250° C., an ammonium halide of the amine of the formula (2) being formed as a byproduct in addition to aminoorganyltriorganylsilane of the formula (1), b) adding a base (B), as a result of which amine of the formula (2) is liberated and a halide of the base (B) forms, the halide of the base (B) being liquid at a temperature of not more than 200° C., and c) removing the halide of the base as a liquid from a phase containing the aminoorganyltriorganylsilanes.
