测定了α-氰基苄基碳负离子钠盐与碳酸二乙酯缩合反应产物的结构及其分布,反应中间体的EPR谱,反应过程中产物和溶剂的CIDNP效应和反应动力学,为这一缩合反应提出了单电子转移-负离子自由基分解-自由基偶合的非链式自由基机理。
The structure and distribution of the condensation products of α-cyanobenzylcarbanionic sodium salt with diethyl carbonate, the EPR spectrum of the reaction intermediates, the CIDNP effect of the product and the solvent during the reaction and the reaction kinetics were determined. The condensation reaction proposed a single electron transfer - anion free radical decomposition - free radical coupling free radical mechanism.
