α-羰基重氮化合物的卡宾聚合反应(C1聚合反应)是近年发展起来的一类合成碳链聚合物的新反应类型,为合成碳链上每一个碳原子都连接有极性取代基的高度功能化聚烯烃类似物提供了烯烃聚合(C2聚合)无法替代且更为便捷有效的新途径,在功能高分子领域有广阔应用前景。本文详细描述了重氮乙酸酯、重氮乙酰胺和α-重氮酮等化合物在铜、钯、铑等过渡金属催化下的卡宾聚合反应及其反应机理,论述了α-重氮化合物参与的共聚合反应以及双-α-羰基重氮化合物的卡宾聚合反应和共聚合反应。最后,展望了卡宾聚合反应的发展趋势。
Carbene polymerization of α-carbonyldiazonium compounds (C1 polymerization) is a new type of reaction of a class of synthetic carbon chain polymers developed in recent years. It is the height of the polar substituent to which each carbon atom in a synthetic carbon chain is linked Functionalized polyolefin analogues provide a new and irreplaceable alternative for olefin polymerization (C2 polymerization), which has broad application prospects in the field of functional polymers. In this paper, the carbene polymerization reactions of diazoacetic acid esters, diazoacetamide and α-diazo ketone catalyzed by transition metals such as copper, palladium and rhodium and their reaction mechanism are described in detail. The effects of α-diazo compounds involved And the carbene polymerization and copolymerization of bis-α-carbonyldiazo compounds. Finally, the development trend of carbene polymerization is prospected.
