Abstract

This manuscript describes the development of the Ni/dcype-catalyzed enolate dance/coupling reaction of alkenyl pivalates with nucleophiles, resulting in cine-substitution. Pivalates derived from 1-tetralone undergo this reaction to produce C2-functionalized dihydronaphthalenes. The direct utilization of 1-tetralone is also feasible, employing Piv₂O to generate the corresponding enol pivalate in situ. Mechanistic investigations, including stoichiometric experiments, suggest that the reaction proceeds via C–O oxidative addition, nickel 1,2-translocation, and subsequent coupling with a nucleophile.

烯醇盐的络氨酸取代：镍催化下环烯基新戊酸酯的烯醇舞/偶联反应

本手稿介绍了镍/dcype催化的烯基新戊酸酯与亲核物的烯醇舞/偶联反应的发展情况，该反应导致了嗪取代。由 1-四氢萘酮（1-tetralone）衍生的新戊酸酯经过该反应生成 C2 功能化的二氢萘。直接利用 1-四氢萘酮也是可行的，利用 Piv2O 在原位生成相应的烯醇新戊酸酯。包括化学计量学实验在内的机理研究表明，该反应是通过 C-O 氧化加成、1,2-镍移位以及随后与亲核剂偶联进行的。
