โœฆ Synopsis

Unsymmetrical diphosphenes carrying bulky alyl and phenoxy groups were prepared by the reaction of lithium 2,4,6-tri-t-butylphenylphosphide with the corresponding phenyl phosphorodichbridites, followed by the dehydrochlorination reaction with 1,g-diazabicyclo[5.4.0]undec-7-ene. The diphosphenes were isolated as stable compounds. The reactions of these diphosphenes with elemental sulfur or selenium afforded the corresponding thiadiphosphiranes or seknadiphosphiranes, respectively. The diphosphenes also reacted with dichlorocarbene to give dichlorodiphosph iranes .

The 2,6-dimesityl-4-[bis(4-methoxyphenyl)amino]phenyl group was developed as a sterically protecting group carrying a reversible redox site at the 4-position and was applied to the construction of a novel redox system composed of the diphosphene and triarylamine units.
