The crystal structure of cis-4,6-dimethyl-2-oxo-2-triphenylmethyl-1,3,2-dioxaphosphorinan

Abstract

The crystal structure of cis-4,6-dimethyl-2-oxo-2-triphenylmethyl-1,3,2-dioxaphosphorinan shows the 1,3,2-dioxaphosphorinan ring to be much more distorted than in related structures, and to have the ‘half-chair’ conformation.
