An organic dye-catalyzed visible light-promoted ketocarbonylation protocol of vinyl arenes has been disclosed with the help of α-bromocarbonyls where aerial oxygen played a role of an oxidant to install the keto-oxygen functionality. This unique process i

A new method for generation of reactive α-ketomethyl aryliodonium intermediates from silyl enol ethers and PhIO*HBF4 has been developed.Reactions of PhIO*HBF4/silyl enol ether adduct with alkenes (1-hexene, cyclohexene, α-methylstyrene, allyltrimethylsilane, 2,3-dimethyl-2-butene) yielded products of allylic alkylation or (in case of 2,3-dimethyl-2-butene) a substituted dihydrofuran.Reactions of adducts from PhIO/HBF4 and silyl enol ethers of acetophone, p-chloroacetophenone, p-methylacetophenone, and p-nitroacetophenone with various silyl enol ethers led to unsymmetrical 1,4-butanediones as major products.
