4-MeC6H4I-mediated efficient -tosyloxylation of ketones with oxone and p- toluenesulfonic acid in acetonitrile
Tanaka, Ayumi,Togo, Hideo
experimental part, p. 3360 - 3364 (2010/03/03)
Various alkyl aryl ketones, dialkyl ketones, and cycloheptanone were efficiently converted into the corresponding -tosyl-oxy ketones in good yields by using Oxone and p-toluenesulfonic acid monohydrate in the presence of p-iodotoluene in aceton

N-Methyl-O-tosylhydroxylamine is an effective reagent for the direct α-oxytosylation of carbonyl compounds. The reactions proceed smoothly at room temperature in the presence of both moisture and air and functional group tolerance in the substrate is good. With nonsymmetrical substrates regioselectivity for primary over secondary centers is observed and complete regiospecificity for primary over tertiary centers is obtained. Addition of a bis-heteronucleophile directly to the crude reaction mixture in a one-pot process leads to the corresponding heterocyclic product.
Ultrasound Promoted Hypervalent Iodine Reactions: α-Tosyloxylation of Ketones with Benzene
Tuncay, Atilla,Dustman, John A.,Fisher, George,Tuncay, Crystal I.,Suslick, Kenneth S.

Ultrasound enhances substantially the rats of α-tosyloxylation of ketones with benzene and thus provides a direct, quick, and mild method of tosyloxylation of ketones without the generation of timeconsuming intermediates such as tri
