Palladium pincer complexes directly catalyze the redox coupling reactions of functionalized alkenes and iodonium salts. The catalytic process, which is suitable for mild catalytic functionalization of allylic acetates and electron-rich alkenes, probably occurs through Pd(IV) intermediates. Due to the strong metal-ligand interactions, the oxidation of phosphine and amine ligands of the pincer complexes can be avoided in the presented reactions.
钯钳形配合物直接催化功能化烯烃与碘鎓盐的氧化还原偶联反应。该催化过程适用于烯丙基乙酸酯和富电子烯烃的温和催化官能化,可能通过钯(IV)中间体发生。由于强烈的金属-配体相互作用,在所展示的反应中可以避免钳形配合物的膦和胺配体的氧化。
