Coupling of propylene sulfide (PS) and carbon disulfide (CS2) catalyzed by the asymmetrical Cr(III)-bis-Schiff-base complex

The pre-activated mixture of Cr(III)-bis-Schiff-base complex 1 and [PPN]Cl was showed to efficiently catalyze the coupling of PS and CS2, giving high poly[thrithio]carbonate selectivity especially upon 2 eq. of CS2 to PS.60
