While carbon-heteroatom cross-coupling reactions have been extensively studied, many methods are specific and limited to a particular set of substrates or functional groups. Reported here is a general method that allows for C-O, C-N and C-S cross-coupling reactions under one general set of conditions. We propose that an energy transfer pathway, in which an iridium photosensitizer produces an excited
尽管碳杂原子交叉偶联反应已得到广泛研究,但许多方法是特定的,并且仅限于特定的一组底物或官能团。这里报道的是一种通用方法,它允许在一组通用条件下进行CO,CN和CS交叉偶联反应。我们提出一种能量转移途径,其中铱光敏剂产生激发的镍(II)络合物,这是关键的还原消除步骤,该步骤将芳基溴化物,碘化物和氯化物与1°和2°的醇,胺,硫醇偶联,氨基甲酸酯和磺酰胺,并且可以通过流动装置放大。
