Abstract
Rare 1,6-C H insertion of naphthol- and anthrol-derived alkylidenecarbenes has been observed in modest yield. Reaction in deuterated solvent did not p rovide any evidence in support of a reaction mechanism that requires exchan ge of the migrating proton with solvent. The pyran-annelated aromatic produ cts are formed only when opportunities for the more common 1,5-C-H insertio n process are blocked. (C) 2001 Published by Elsevier Science Ltd.
