  摘要：

  The generation of (2-PyMe2Si)(2)CHLi was easily accomplished by the deprotonation of (2-PyMe2Si)(2)CH2 using n-BuLi in Et2O. Thus generated (2-PyMe2Si)(2)CHLi was found to react with a variety of aldehydes and ketones to give the corresponding vinylsilanes in extremely high yields with complete stereoselectivities.

  (2-PyMe2Si)2CHLi in Et2O-d10 revealed the coordination of both pyridyl groups to lithium. Thus generated (2-PyMe2Si)2CHLi was found to react with a variety of aldehydes and ketones to give the corresponding vinylsilanes in extremely high yields with complete stereoselectivities (>99% E).

  的产生（2- PyMe 2 Si）的2 CHLi容易被（2- PyMe的去质子化来实现2 Si）的2 CH 2使用Ñ在Et正丁基锂2 O的1（2- PyMe的H NMR分析2的Si ）Et 2 O- d 10中的2 CHLi显示两个吡啶基均与锂配位。发现由此生成的（2-PyMe 2 Si）2 CHLi与多种醛和酮反应，以极高的收率和完全的立体选择性（> 99％E）得到相应的乙烯基硅烷。
