Abstract

A switchable, solvent-free catalytic system was developed in which Al methyl aminebis(phenolate) catalysts selectively initiate the formation of a polyether from cyclohexene oxide under CO₂ atmosphere or the ring opening copolymerisation (ROCoP) of cyclohexene oxide and CO₂ through the addition of a PPNCl (bis(triphenylphosphine)iminium chloride) cocatalyst to form poly(cyclohexene carbonate).

用于开环聚合反应的可切换手性铝催化剂

开发了一种可切换的无溶剂催化系统，其中 Al 甲基胺双（苯酚）催化剂可选择性地在 CO2 气氛下从环己烯氧化物中生成聚醚，或通过添加 PPNCl 助催化剂从环己烯氧化物和 CO2 的 ROCoP 中生成聚（环己烯碳酸酯）。
