Ruthenium-catalyzed cross-dehydrogenative C-H bond alkenylations occurred efficiently in environmentally benign water, which was exploited for an oxidative phthalide synthesis with ample scope. Mechanistic studies provided strong evidence for the oxidative alkenylation to proceed by an irreversible C-H bond metalation via acetate assistance.
钌催化的交叉脱氢 C-H 键烯丙基化反应在环境友好的水中高效发生,这为具有广泛应用前景的氧化邻苯二甲酸酐合成提供了条件。机理研究为通过乙酸盐辅助的不可逆 C-H 键金属化进行氧化烯丙基化反应提供了有力证据。
