Transposition des bromo-2 benzenepropionates d'ethyle, substitues en α par un groupe acetyl ou cyano, en acetyl-2 et cyano-2 benzenepropionate d'ethyle. Synthese d'oxo-3 cyclanecarboxylates d'alkyle a partir de β-cetoesters; par exemple l'iodomethyl-2 oxo-2 cyclopentanecarboxylate d'ethyle conduit a l'oxo-3 cyclohexanecarboxylate d'ethyle

The reaction of 2-substituted cycloalkanones with cerium(IV) sulfate tetrahydrate (CS) in alcohols and acetic acid gave the corresponding alkyl esters of oxo acids (80—96%) and oxo acids (78—96%), respectively, by oxidative cleavage of the C(R)–C=O bond. In the case of 2-iodocycloalkanones in methanol, the dimethyl ester was obtained in good yield. A treatment of 5α-cholestan-3-one with CS in methanol
