## Abstract Carbon‐13 NMR data are reported for a series of 1,2‐diaryl‐4‐oxo‐4,5,6,7‐tetrahydroindoles, 6‐methyl‐2‐phenyl‐4‐oxo‐4,5,6,7‐tetrahydrobenzofuran and 1‐,6‐dithiaindan‐4‐one. The chemical shifts δ 193–196, δ 195.5 and δ 184 are identified for the carbonyl carbon (C‐4) in the tetrahydroind
