Synthesis of poly (imino ketone)s by palladium catalysis C-N cross-coupling reaction

Synthesis

Abstract

In this paper, taking Pd2(dba)3 as catalyst and 2,2′-bis-(diphenylphosphino)-1,1′-binaphtyl as ligand, six kinds of poly(imino ketone)s (PIKs) with different structures have been synthesized via palladium catalysis C-N cross-coupling reaction. The structures of polymers synthesized was characterized by means of FTIR and NMR spectroscopy, the results showed an agreement with the proposed structures. The influential disciplines of monomer concentration and catalysis system to PIKs molecular weight were discussed. Differential scanning calorimetry measurement showed that PIKs possessed high glass transition temperatures (T g > 150°C).
