A reinvestigation of the intramolecular Buchner reaction of 1-diazo-4-phenylbutan-2-ones leading to 2-tetralones
Abstract
Rhodium acetate-catalysed decomposition of 1-diazo-4-(2-methoxyphenyl)butan-2-one 8 leads, after rearrangement under acidic conditions, to 5-methoxy-2-tetralone 13 and not to 8-methoxy-2tetralone 10 as reported.
