alpha-phenylsulfonyl-N-arylacetamides (alpha-phenylsulfonylacetanilides): H-1,C-13 and N-15 NMR spectral characterization

H-1 and C-13 NMR chemical shift assignments for 11 alpha-phenylsulfonylacet anilides and N-15 NMR chemical shifts for four representative congeners are reported. The H-1 and C-13 chemical shift assignments are based on DQF COS Y and PFG H-1,C-13 HMQC/HMBC experiments. The N-15 NMR chemical shifts were determined by PFG H-1,N-15 HMBC experiments. The correlation analyses with Hammett-type substituent constants gave a significant result with delta(C- 1) in the aniline ring. Copyright (C) 2000 John Wiley & Sons, Ltd.
