摘要：
The synthesis of various vinylbis(silanes) from some aryl and heteroaryl aldehydes and (Me(3)Si)(3)CLi in Et(2)O is described. Friedel-Crafts reaction of 1,1-bis(trimethylsilyl)-2-(2-naphthyl)ethene with various acyl chlorides (RCOCl, R = Me, Et, i-Pr, i-Bu, n-pent) gave the corresponding alpha-silyl-alpha,beta-unsaturated enones with high E steroselectivity. Moreover, poly(styrene)-co-[2,2-bis(trimethylsilyl)ethenyl(styrene)] obtained via the reaction of polymers bearing pendant enone functions and (Me(3)Si)(3)CLi, reacts with the same acyl chlorides in the presence of catalytic amount of AlCl(3) to give the new macromolecules bearing alpha-silyl-alpha,beta-unsaturated enones and alpha,beta-unsaturated enones.
