In the manuscript, a novel method for the preparation of cyclopent-1-enecarbonitriles via tandem Giese/HWE reaction initiated by visible light in the presence of fac-Ir(ppy)3 as a photocatyst has been described. The cascade reactivity combining radical and polar processes has proven applicable for a wide range of N-(acyloxy)phthalimides (which serve as precursors of the corresponding radicals) as well
在手稿中,描述了一种在fac -Ir(ppy) 3作为光催化剂存在的情况下,通过可见光引发的串联 Giese/HWE 反应制备环戊-1-烯腈的新方法。结合自由基和极性过程的级联反应已证明适用于范围广泛的N- (酰氧基) 邻苯二甲
酰亚胺(作为相应自由基的前体)以及
二乙基 ( E )-(1-
氰基-2-芳基
乙烯基)
膦酸酯. 导致所述策略成功的关键参数是:可见光、1 mol% 的光氧化还原催化剂、碱、无
水溶剂和惰性气氛。反应产生新的 sp 3 –sp 3和sp 2 –sp 2碳-碳键在温和条件下的形成。
