transformation of alkynyl- and allenyl-containing substrates has emerged as a powerful tool to achieve this objective. Herein, an efficient copper-catalyzed difunctionalization of propargylic carbonates through tandem nucleophilic substitution/boroprotonation has been developed, affording the formation of thiol-, selenium-, and boron-functionalized alkenes with high yield and stereoselectivity. Two distinct catalytic
高功能化有机分子的需求量很大,但其制备具有挑战性。含炔基和丙二烯基底物的铜催化转化已成为实现这一目标的有力工具。在此,开发了一种通过串联亲核取代/硼质子化的有效铜催化炔丙碳酸酯双官能化反应,以高产率和立体选择性形成硫醇、硒和硼官能化烯烃。成功证明了两种不同的催化机制,涉及单一反应,无需更换催化剂。
