enolizable ketones. Regioselective α- or γ-oxygenated carbonyl compounds were obtained smoothly at ambient temperature in moderate to good yields. Oxyfunctionalization of (+)-carvone and (−)-carvone proceeded stereoselectively, and provided cis-product (5R, 6S)- and (5S, 6R)-2-cyclohexen-1-ones, respectively. Interestingly, unsymmetricalketones afforded isomeric α- and α′-oxygenated ketones, while allyl
Several bis-1,3-dithiolium salts, radical cation salts of tetrathiafulvalene were synthesized in quantitative yields by oxidation of tetrathiafulvalene with oxoaminium salts for 1min at room temperature.
