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.
Me2HSiCH2CH2CH2Cl reacts with primary alkyl, aryl or aralkyl amines to form the corresponding 1-aza-2-silacyclopentanes Me2R. It seems that the ease of ring closure is a result of enhanced reactivity of the SiH bond of the intermediate [Me2HSiCH2CH2CH2NHR] arising from intramolecular Si ⋯ N interaction.
