  A general synthesis of vinylic silyl hydrides using nickel catalysis. Applications to the syntheses of silylene-tethered conjugated polymers

  摘要：

  Treatment of benzylic or allylic dithioacetals with Me-2((PrO)-Pr-i)SiCH2MgCl in the presence of NiCl2(PPh3)(2) catalyst yielded the corresponding i-propoxy(vinyl)silanes which are reduced with LIAlH4, to afford vinylic silyl hydrides. These hydrides serve as the precursors for the syntheses of silylene-tethered sigma,pi-conjugated copolymers. (C) 1998 Elsevier Science Ltd. All rights reserved.

  4-bis[dimethyl(i-propoxy)silyl]vinyl}benzene (3) with water in the presence of base results in the formation of a siloxane tethered paradivnylbenzene cyclophane 2. The structure of 2 was confirmed by X-ray crystallography. UV and fluorescence spectra were measured and interaction between chromophores may occur.
