A palladium-catalyzed intramolecular C-H bond sulfuration reaction of aryl thiocarbamates has been developed. This strategy provides a new route to benzo[d][1,3]oxathiol-2-ones with tolerance of a wide range of substituents. Mechanistic studies suggested

Bu3N/AlCl3-promoted [3+2] cyclocondensation between phenols and chlorocarbonylsulfenyl chloride (CCSC; 3) gave 1,3-benzoxathiol-2-ones (2), wherein the acylation of phenols with CCSC (3) and the intramolecular and regioselective ortho-sulfenylation successively proceeded in a one-pot manner. 2-Sulfanylphenols (1) were produced from 2 by mild hydrolysis using NaOH. An analogous Bu3N-promoted [3+2] cyclocondensation between ketones and 3 gave 1,3-oxathioles (7), wherein the α-CH2- position of the ketones was regioselectively sulfenylated.
