1H and 13C NMR chemical shift assignments for 11 α‐phenylsulfonylacetanilides and 15N NMR chemical shifts for four representative congeners are reported. The 1H and 13C chemical shift assignments are based on DQF COSY and PFG 1H,13C HMQC/HMBC experiments. The 15N NMR chemical shifts were determined by PFG 1H,15N HMBC experiments. The correlation analyses with Hammett‐type substituent constants gave
报告了 11 α-苯基磺酰乙酰苯胺的 1H 和 13C NMR 化学位移分配以及四种代表性同源物的 15N NMR 化学位移。1H 和 13C 化学位移分配基于 DQF COZY 和 PFG 1H,13C HMQC/HMBC 实验。15N NMR化学位移由PFG 1H,15N HMBC实验确定。与哈米特型取代基常数的相关性分析给出了苯胺环中 δ(C-1) 的显着结果。版权所有 © 2000 John Wiley & Sons, Ltd.
