Enabling reactions of traditional substrates that are inert to Pd catalysts has the potential for further advancements in the field of Pd chemistry. In this study, we developed a method for generating ketyl radicals through the reaction of a photoexcited Pd species with ketones. Upon subsequent reaction with olefins, the ketyl radicals generated through this method yielded Pd-specific reductive and

钯催化剂呈惰性的传统基质发生反应具有在
钯化学领域进一步发展的潜力。在这项研究中,我们开发了一种通过光激发的
钯物质与酮反应产生羰基自由基的方法。随后与烯烃反应时,通过该方法产生的羰基自由基产生了 Pd 特异性还原和 Heck 型偶联产物。机理研究表明,所提出的自由基生成方法表现出与SmI 2还原和光氧化还原催化反应等传统方法不同的特征。
