conditions. Mechanistic investigations and density functional theory (DFT) studies suggest that a photoinduced inner‐sphere mechanism is operative in which a barrierless, single‐electron transfer oxidative addition of the alkyl halide to Pd0 is key for the efficient transformation.
描述了可见光诱导的,钯催化的未活化烷基溴化物对α,β-不饱和酸的烷基化作用。各种伯,仲和叔烷基溴化物被光激发的钯金属催化剂活化,在室温下在温和的反应条件下提供一系列烯烃。机理研究和密度泛函理论(DFT)研究表明,光致内球机理是有效的,其中无卤,单电子转移的烷基卤化物向Pd 0的氧化加成是有效转化的关键。
