A general catalytic protocol for the halodecarboxylation of aliphatic carboxylic acids via ligand-to-metal charge transfer (LMCT) is presented. This conversion is capable of transforming primary, secondary, and tertiary alkyl acids into the corresponding bromo-, iodo- and chloroalkanes using water as a solvent under an air atmosphere. The broad range of substrate scope, the use of a green solvent,
提出了通过配体到金属电荷转移(LMCT)进行脂肪族羧酸卤代脱羧的通用催化方案。该转化能够在空气气氛下用水作为溶剂将伯、仲和叔烷基酸转化为相应的溴代烷烃、碘代烷烃和氯代烷烃。广泛的底物范围、绿色溶剂的使用以及衍生药物分子和天然产物的能力为脱羧卤化反应提供了新的前景。
