The O‐17 NMR spectra of 13 α′‐alkyl‐ and aryl‐substituted α‐diazoketones were measured. The results obtained show a clear discrimination between them. A good correlation in a series of para ‐substituted α‐diazoacetophenones between O‐17 chemical shifts and both α + p and dual substituent parameters indicated a greater contribution of resonance than inductive effects.
