2‐Isopropyl‐6‐phenyl‐ and 2,6‐diisopropyl‐pyridiniums with bulky 1‐substituents show temperature‐variable NMR spectra which are interpreted in terms of restricted rotation. 2‐Isopropyl‐4,6‐diphenylpyrylium can be deprotonated at the isopropyl group to give an anhydro base which forms new pyryliums with electrophiles.
