acetates, and NBS, under Ru(II)/Ru(IV) catalysis has been developed. Using 1H NMR, ESI-MS, HRMS, control reactions, deuterium labeling experiments, and DFT analysis, the allyl transfer (redox) process was proven to involve in C–H allylation rather than olefin insertion. Scale-up and synthetic transformations demonstrated the sustainability of this method.
已经开发出在 Ru( II )/Ru( IV ) 催化下,使用N -芳酰基氨基酯、MBH 乙酸酯和 NBS,合并 C(sp 2 )–H 烯丙基化和烯烃双官能化事件以获得异色满-1-亚胺。使用1 H NMR、ESI-MS、HRMS、对照反应、氘标记实验和 DFT 分析,烯丙基转移(氧化还原)过程被证明涉及 C-H 烯丙基化而不是烯烃插入。放大和合成转化证明了该方法的可持续性。
