Treatment of cyclopentanone and cyclobutanone-derived oximes with lead (IV) tetraacetate gives the bright blue acyloxy nitroso compounds, which upon basic hydrolysis yields the ring expansion product cyclic hydroxamic acids in 12-81% yield. Reactions of substituted cyclopentanones provide ring expanded products where the -NOH group regioselectively inserts to the more substituted position and gives a better yield compared to the treatment of the same ketone with a basic solution of Piloty's acid ...[more]
