Abstract
The synthesis of 2,5,1-benzoxazasilepines 3 or the benzoxazasilaspiro compound 4, has been achieved by the reaction of o-lithio-N-(2-lithioo xyethyl)-N-methyl-aniline (2) with R2SiCl2 (R = Me, Et, Ph) or SiCl4, respectively. The reaction led to the formation of cyclic products, ev en under conditions favorable for the formation of polymeric materials . (C) 1997 Elsevier Science Ltd.
