Ruthenium(II) oxidase catalysis by direct dioxygen‐coupled turnover enabled step‐economical oxidative CH alkenylation reactions at ambient pressure. Versatile ruthenium(II) biscarboxylate catalysts displayed ample substrate scope and proved applicable to weaklycoordinating and removable directing groups. The twofold CH functionalization strategy was characterized by exceedingly mild reaction conditions

Ruthenaelectro(II/IV)-catalyzed intermolecular C–H acyloxylations of phenols have been developed by guidance of experimental, CV and computational insights. The use of electricity bypassed the need for stoichiometric chemical oxidants. The sustainable electrocatalysis strategy was characterized by ample scope, and its unique robustness enabled the late-stage C–H diversification of tyrosine-derived
在实验、CV 和计算见解的指导下,开发了钌电 ( II / IV ) 催化的酚分子间 C–H 酰氧基化反应。电力的使用绕过了对化学计量化学氧化剂的需求。可持续电催化策略的特点是范围广泛,其独特的鲁棒性使得酪氨酸衍生肽的后期C-H多样化成为可能。
