crystalline salts with 8-acetyl- and 8-benzoyl-naphthol which show O⋯C distances for the anions in the range 2.558–2.618 Å and small increases in carbonyl pyramidalities over the corresponding naphthols, whereas DMAP forms only hydrogen bonded complexes. Replacement of the acyl group with an alkene leads to intramolecular O–C bondformation for just the most electron deficient alkenes, with long peri O–C
