The decarboxylative alkynylation of (hetero)aryl carboxylic acids with terminal alkynes has been achieved by using a Pd(PPh3)4/PCy3 catalyst. This Pd-catalyzed method exhibits good functional group tolerance for both coupling partners and enables chemical modification of complex molecules. The establishment of this decarboxylative alkynylation reaction is attributed to the discovery of a highly selective
通过使用Pd(PPh 3)4 / PCy 3催化剂,已实现了(杂)芳基羧酸与末端炔烃的脱羧烷基化反应。这种Pd催化的方法对两个偶合伙伴均具有良好的官能团耐受性,并且能够对复杂分子进行化学修饰。该脱羧炔基反应的建立归因于发现了(杂)芳基羧酸与NBS(N-溴代琥珀酰亚胺)的高选择性脱羧溴化。
