摘要

Abstract

The acylation of bromobenzene with 3-(4-bromophenyl)-3-chlorophthalide gave 3,3-bis(4-bromophenyl)phthalide which was used as a monomer to obtain poly(diphenylenephthalide) {poly(3-oxo-1H2-benzofuran-1,1-diyl[1,1′-biphenyl]-4,4′-diyl} by polycondensation via the Ni(0)-catalyzed coupling. The described reaction provides a new synthetic approach to poly(arylenephthalides).
