Abstract

3-Aryl-3-trimethylsilylcyclopropenes (1) were synthesized by a four-step reaction sequence starting from known benzoyl trimethylsilanes. These cyclopropenes were thermalized on a gas chromatography column and the products were collected and identified. Their 1, 2- dibenzoyl derivatives (2) were prepared in a two-step transformation beginning with 3-aryl-1, 2, 3-tris (trimethylsilyl) cyclopropenes (5), the ultimate intermediates in the syntheses of 1. ...
