We have developed a new method for the synthesis of 2-substituted benzimidazoles via amidinyl radicals generated by visible-light-promoted reduction of N-phenyl amidoxime esters in the presence of an iridium photocatalyst. This is the first report of the use of N-phenyl amidoxime esters as amidinyl radical precursors, and the first use of substituted benzene rings as amidinyl radical acceptors. This

An oxidative formation of 1,4,2-oxathiazoles from readily available thiohydroximic acids is reported. A variety of alkyl, aryl, and heteroaryl substituents are well tolerated for both the thiohydroximic acid and activating fragments, and the reaction has been demonstrated on gram-scale. This reaction represents the only method currently available to prepare a diverse set of oxathiazoles and expands the chemistry of C-H oxidation via appended N-OH functional groups. Finally, we also demonstrate the rapid preparation of a 1,4,2-oxathiazole analog of an anticancer lead molecule.

An improved and expanded preparation of thiohydroxamic acids is reported along with a one-pot conversion of these compounds to novel thiohydroximic acid derivatives. A variety of aryl, heteroaryl, and alkyl substituents are well tolerated to provide a rapid approach to alkene-functionalized thiohydroximic acids that serve as potentially useful building blocks for organic synthesis.
