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.
## Abstract Sterically crowded triarylphosphines and tetraaryldiphosphane bearing phenothiazinyl groups as redox sites were synthesized by using 2βbromoβ1,3βdialkylβ5βphenothiazinylbenzenes as key synthetic intermediates. Cyclic voltammograms of these compounds show the first redox wave correspondi
