α-Alkyl-α-aminosilanes: Synthesis via Alkylation and Hydrosilylation

The readily available aminomethylsilanes can be utilized to prepare the less available α-alkyl-α-aminosilanes. Versatile t-butoxy-carbonal (Boc) derivatives can be metalated between nitrogen and silicon, and then alkylated by an electrophile at this position. Two alternative procedures were also developed, including an aza-reverse-Brook rearrangement of metalated N-silylcarbamates and hydrosilylation of N-alkenylcarbamates. © 1997 by John Wiley & Sons, Ltd.
