Abstract

Abstract-The use of N,N-dimethylhydrazine or its trimethylsilyl derivatives in silylation, silamethylation, silethenation, and transsilylation allows synthesis of previously unknown linear and heterocyclic compounds. ... Primary amines react with (chloromethyl)dimethyl- silanes I to form 2,5-disilapiperazines II or their mix- ture with 2,6-disilapiperazines III [133]. ... Me N(R)CH2 CH2N(R) Si ... + RNQSSi(Me)2CH2 Si(Me2)CH2QSNR III R = Pr, All, Bu, i-Bu, ...
