摘要

Abstract The proton and carbon NMR spectra of nine 4-X-diphenyl sulphides (series 1), seven 4-X-4′-NO 2-diphenyl sulphides (series 2) and eight 4, 4′-X 2-diphenyl sulphides (series 3) have been obtained. Correlation of the 13 C chemical shifts with the appropriate substituent chemical shifts (SCS) for monosubstituted benzenes (Lynch plots) show an enhancement of substituent effect at C-1 (carbon para to the substituent) in series 1 and 2, ...
