The first Fe-facilitated decarboxylative cross-coupling reaction between α-oxocarboxylic acids and acrylic acids in aqueous solution has been developed. This transformation is characterized by its wide substrate scope and good functional group compatibility utilizing inexpensive and easily accessible reagents, thus providing an efficient and expeditious approach to an important class of α,β-unsaturated
已经开发出水溶液中α-氧代羧酸与丙烯酸之间的第一个铁促进的脱羧交叉偶联反应。该转化的特征在于其底物范围宽和使用廉价且易于获得的试剂的良好官能团相容性,从而为生物活性化合物中常见的重要一类α,β-不饱和羰基化合物提供了一种有效而快捷的方法。在随后的官能化反应中也证明了偶联产物的合成潜力。初步的机理研究表明,该过程涉及自由基途径:
