THE REACTION OF PHOSPHITE ESTERS AND TRIS(DIMETHYLAMIN0)PHOSPHINE WITH 1,4- NAPHTHOQUINONEMONOBENZENESULFONIMINE

Trimethyl and triisopropyl phosphites react with quinoneimine III to give the corresponding phosphonate derivatives having structure IV) Tris(dimethylamino)phosphine, on the other hand, attacks the carbonyl oxygen of III, yielding the dipolar structure VIII. Possible reaction mechanisms are considered and the structural assignments are based on chemical and spectroscopic evidence.
