Dilithium diphenylmethanediide; generation, redox relationship with lithium chlorodiphenylmethanide, implication with regard to aggregation

Abstract

Dilithium diphenylmethanediide, Ph₂CLi₂, prepared by reaction of dichlorodiphenylmethane with lithium p,p′-di-tert-butylbiphenyl, reacts with organic halides and carbonyl compounds to give lithium Chlorodiphenylmethanide, Ph₂CLiCl, as a major product and is assumed to exist in two different states of aggregation.
