The present invention relates to a method for the preparation of 1-aza-2-silacyclopentane compounds whose nitrogen is substituted by a hydrocarbon group or a heteroatom-containing hydrocarbon group. The method comprises effecting an intramolecular hydrosilylation reaction of a N,N-disubstituted aminosilane. In a preferred method, the intramolecular hydrosilylation reaction is conducted in the presence of a rhodium-containing catalyst.
La présente invention concerne une méthode de préparation de 1-aza-2-silacyclopentanes dont l'atome d'azote porte un groupement hydrocarboné ou un groupement hydrocarboné contenant un hétéroatome. Cette méthode comprend la réalisation d'une réaction d'hydrosilylation intramoléculaire d'un aminosilane dont l'atome d'azote est bisubstitué. La réaction d'hydrosilylation intramoléculaire est réalisée, de préférence, en présence d'un catalyseur au rhodium.
