The arylation of aromatic diamines with arylhydrazine hydrochlorides was achieved in reasonable yields. This new and simple reaction occurred at room temperature in air using an inexpensive base. This transformation seems to proceed via a homolytic aromatic substitution (HAS) mechanism. The synthesized aromatic diamines are used as raw materials for polyimides, including important aerospace materials, for example, Kapton

Some observations on T.Cohen's method for coupling 2-iodonitrobenzenes to 2,2'-dinitrobiphenyls are reported.A general method for making 2',2"-di-iodo-m-quaterphenyls from the 2',2"-diamines, reported in Part 2, features decomposition of the bis-diazonium iodomercurates to dibenziodolium iodomercurates and pyrolysis of the latter.The procedure can be used to prepare other aryl iodides. 2',2"-Di-iodo-m-quaterphenyls, on succsessive treatment with butyl-lithium, phosphorus trichloride, water, and hydrogen peroxide, yield 4,6-diaryl-5-hydroxydibenzophosphole 5-oxides, three of which were prepared.Te structures of two derivatives of these, 2,8-dichloro-3,7-di(2-hydroxyethoxy)-5-methoxy-4,6-diphenyldibenzophosphole 5-oxide and 5-hydroxy-3,7-dimethoxy-4,6-di-(4-methoxy-3,5-di-t-butylphenyl)dibenzophosphole 5-oxide, have been determined by X-ray crystallography and are reported in the Appendix.
