2-halomethyl cycloalkanones

Radical-mediated ring expansion of 2-halomethyl cycloalkanones. [Pg.210]

Bicyclo[n.l.O]alkan-l-oxyl radicals are fleeting intermediates in homolytic reactions of 2-(halomethyl)cycloalkanones and related radical precursors. Unrearranged 2-methyl-cyclohexanone (19) was obtained from treatment of 2-[(phenylselanyl)methyl]cyclohexanone (18) with tributyltin hydride. ... [Pg.2444]

The starting 2-(halomethyl)cycloalkanones 54 (X = Br, I), were easily prepared by treatment of the corresponding cyclic / -oxo esters with base (usually sodium hydride), followed by alkylation with dibromo- or diiodomethane. Yields for the ring expansion were good, and the process worked well, even for 15-membered rings " and large bicycloalkanes. ... [Pg.2481]
