Description
Summary:The condensation of O-phenylenediamine (OPD) with aryl aldehydes is carried out in acetonitrile using poly(N,N′-dibromo-N-ethylnaphthyl-2,7-disulfonamide) (PBNS) as a novel and heterogeneous catalyst. PBNS has some potential advantages which include ease of separation from the reaction mixture by simple filtration, easy preparation, recoverablility, convenience, and stability under normal condition and also is not dangerous as molecular bromine.
