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.
