A series of single-component cobalt salen complexes, N,N 0 -bis(salicylidene)-1,2phenylenediamino cobaltIII X (X ΒΌ Cl (1a), Br (1b), NO3 (1c), CF3COO (1d), BF4 (1e), and N3 (1f)) (SalphCoX), were prepared for alternating copolymerization of carbon dioxide and propylene oxide(PO) under mild condition
Supercritical carbon dioxide was found to be a suitable substitute for halogenated organic solvents in its copolymerization with propylene oxide. The system was studied utilizing a heterogenous catalyst, zinc glutarate. The polymers were analyzed for selectivity in polycarbonate linkages by 'H NMR s
