Process for the preparation of aminopropylalkoxysilanes in the presence of shaped polymeric rhodium complex catalysts and their use

摘要

In the prepn. of aminopropylalkoxysilanes of formula (I) by reacting hydridosilanes of formula (II) with an amine of formula (III) in the presence of a Rh-complex catalyst with organo-P ligands, the catalyst comprises a moulded polymeric Rh complex catalyst (IV) with organosiloxane monophenylphosphine ligands: R2R3NCH2CHR4CH2Si(OR)3-n(R1)n (I) HSi(OR)3-n(R1)n (II) R2R3NCH2CR4=CH2 (III), R, R1 = 1-8C alkyl; n = 0, 1 or 2; R2, R3 = H, 1-8C alkyl and/or 3-8C omega -alkenyl; R4 = H or 1-8C alkyl. Also claimed is the use of (IV) in the prepn. of (I).
