Abstract

A sterically crowded bromobenzene, 1,2-bis(2-bromo-3,5-di-t-butylphenyl)ethane, was prepared and converted to the corresponding phosphonous dichloride, which reacted with lithium (2,4,6-tri-t-butylphenyl)phosphide to give 1,2-bis[3,5-di-t-butyl-2-{(2,4,6-tri-t-butylphenyl)phosphinidenephosp hino}phenyl]ethane; the photolysis of the compound gave E-bis(2,4,6-tri-t-butylphenyl)diphosphene and an internal Z-diphosphene; the tungsten complex of the latter was analyzed by X-ray crystallography.
