摘要

Abstract 13 C and 17 O NMR data [chemical shifts and 1 J (CH) values] for the methoxy groups in isomeric 1, 2-, 1, 3-and 1, 4-dimethoxybenzenes, 1, 2, 3-trimethoxybenzenes and most of their chlorinated derivatives and some related brominated compounds were measured for CDCl 3 solutions. The 17 O NMR chemical shifts show up to 60 ppm dispersion. Comparison between the compounds with and without adjacent chlorine ...
