The unexpected nucleophilic reactivity of free-radicals generated from α-iodoketones is reported; two different procedures, either employing tin or the more environmentally acceptable ethylsulfone-based coupling reagent 5c have been developed.

Treatment of trimethylsilyl enol ethers with the adduct 1, derived from chloramine-T and (PhS)2, gave good yields of alpha-phenylthioketones. The selenium version of this reagent 2 gave alpha-phenylselenoketones.

of functionalized macrocyclic ketones has been developed. Pyrolysis of medium- and large-ring 3-vinylcycloalkanones by dynamic gas-phase thermo-isomerization (DGPTI) at 600–630° yielded, under insertion of a previously attached vinyl side chain by means of a 1,3-C shift, the corresponding γ,δ-unsaturated cycloalkanones. The yield of the two-carbon ring-expanded ketones greatly depended on the relative
