The silaallyl anion has two major contributing resonance structures; one with the lone pair of electrons located on a silicon atom (1), which can also be viewed as a simple vinyl silyl anion and a second structure with the lone pair of electrons localized on a carbon atom (2).<br/>We are interested in studying vinylsiloles as part of a larger study on the silyl anion. We will present a crystal structure of 1-trimethylsilyl-1-vinyl-2,3,4,5-tetraphenylsilole, 3, and its synthesis. Particular emphasis will be placed on the need for a higher yield synthesis of this compound which we have undertaken following the synthesis of 1-chloro-1,1-diphenyl-2,2,2-trimethyldisale as reported by Tamao.
