The development of highly efficient, recyclable poly(4-vinylimidazolium) iodides (2) for the benzoin condensation reaction under mild reaction conditions is discussed: poly(4-vinylN-heterocyclic carbene)s (3) obtained from2showed a higher catalytic activity and could be successfully recovered and reused over seven times without loss of performance.
讨论了在温和反应条件下,高效可回收的聚(4-乙烯基咪唑)碘化物(2)对苯并酮缩合反应的发展:从2获得的聚(4-乙烯基N-杂环卡宾)(3)表现出更高的催化活性,并且可以成功地回收和重复使用七次以上而不降低性能。
