First Structural Characterization of a Benzophenone Ketyl Complex

Zhaomin Hou, Xueshun Jia, Mikio Hoshino, Yasuo Wakatsuki

Abstract

Highly reactive and yet isolable! The bis(benzophenone ketyl)calcium complex 1 was isolated as blue crystals from the reaction of calcium chips with benzophenone and hexamethylphosphoric acid triamide (HMPA) in THF (see below). Its X-ray crystal structure explains why benzophenone ketyl is much more reactive than fluorenone ketyl.
