Seven novel Hoveyda-Grubbs precatalysts bearing an aminosulfonyl function are reported. Kinetic studies indicate an activity enhancement compared to Hoveyda's precatalyst. A selection of these catalysts was investigated with various substrates in ring-closing metathesis of dienes or enynes and cross metathesis. The results demonstrate that these catalysts show a good tolerance to various chemical functions.
本文报道了 7 种新型带有氨基磺酰基功能的 Hoveyda-Grubbs 前催化剂。动力学研究表明,与 Hoveyda 的前催化剂相比,这些催化剂具有更高的活性。选择了其中一些催化剂,研究了它们在二烯或烯炔的环化复分解以及交叉复分解反应中与各种底物的反应。结果表明,这些催化剂对各种化学官能团具有良好的耐受性。
