III with NaBH4, NaBD4 or CH3Li, and in the reaction of VI with CH3Li, the anion of acetonitrile, the anion of nitromethane or the phenylacetylide anion. Ring opening reactions to give complexed o,o′-disubstituted benzophenones were observed when III was treated with the anion of acetonitrile, the anion of nitromethane, methylamine, cyclohexylamine, benzylamine or pyrrolidine.
