chiral oxazolidinethiones (OZT) and aromatic oxazolinethiones (OXT), were involved, for the first time, in Sonogashira cross-coupling. A cooperative effect of two different copper (I) species-CuI and CuTC-accounts for this new copper-catalyzed desulfurative carbon-carbon cross-coupling reaction. This cooperative reactivity could also be extended to other copper (I) catalysts.

硫酮(OXT)首次涉及Sonogashira交叉偶联。两种不同的
铜(I)物种CuI和CuTC的协同作用说明了这种新的
铜催化的脱
硫碳-碳交叉偶联反应。这种协同反应性也可以扩展到其他
