Abstract
The reaction between 1-hydroxy-2-acetonaphthone and 2-fluorobenzophenone in basic medium afforded two diastereoisomeric carbonyl dyes whose structures were unambiguously established using spectroscopic methods. A mechanism for the formation of these dyes involving a base-catalysed addition followed by dehydration and intramolecular aromatic nucleofilic substitution is proposed.
