Metal ions and complexes in organic reactions. Part XIV. Syntheses of NN′-bisdiarylphenylenediamines

Abstract

The following NN′-bisdiarylphenylenediamines were obtained, together with by-products, from copper-catalysed substitution of iodo-compounds : p-bisdiphenylaminobenzene (II), p-bis-(o-nitro-N-phenylanilino)benzene (IV), and N-(p-diphenylaminophenyl)-o-nitro-N-phenylaniline (III). Compound (III) was identical with a by product previously isolated from a copper-catalysed reaction between diphenylamine and o-bromonitrobenzene.
