Synthesis of Substitued Dibenzophospholes. Part 6. Preparation of Symmetrical and Non-symmetrical Quaterphenyl Intermediates

Further examples are given of the synthetic approach to 4,6-diaryldibenzophospholes by arylation of 1,3-dinitrobenzene and coupling of the resulting biphenyls to symmetrically substituted quaterphenyls.Satisfactory procedures are described for the monoarylation of 2,2',4,4'-tetranitrobiphenyl and for arylation of the products to provide non-symmetrically substituted tetranitroquaterphenyls.Some procedures for the regioselective alkoxydenitration of tetranitroquaterphenyls are described.
