摘要

The mono-σ-bonded organochromium (III) complexes (A) derived from (1) rearrange internally into (B) through an acyl ester group transposition, selected experimental conditions allowing either a good access to the unmasked ortho-hydroxybenzyl ketones (2) or a new route to the 2-substituted benzo [b] furans (3).
