✦ Synopsis

A general method for preparing (arylalkenyl)siianes via nucleophilic capture of arynes with vinyltrimethylsilyl Grtgnard reagents is described.

We recently developed methodology for forming from one to four new aryl-carbon bonds in a one-pot reaction by treating various polyhalobenzenes with aryll , alkeny12g3 and alkyny12 Grignard reagents. In this paper we show how the utility of these reactions can be extended substantially by using Grtgnard reagents with latent functionality, in particular the trimethylsilyl group.4
