摘要：

With an asymmetrical Cr(III)-bis-Schiff-base complex [Cr(L)Cl] (1; H2L. obtained from reaction of HL0 ((Z)-4((2-aminophenylimino)(phenyl)methyl)-3-methyl-1H-pyrazol-5(4H)-one) and 3,5-dibromo-2-hydroxybenzaldehyde) as the catalyst, the [PPN]Cl-assisted ([PPN](+) = [Ph3P = N = PPh3](+)) coupling of PS (propylene sulfide) and CS2 for the formation of poly[trithio]carbonate and [trithio]carbonate was efficiently realized, in which, the pre-activation of catalytic system and the coupling procedure have much influential to poly[trithio]carbonate selectivity.
