This review summarizes the synthesis of diverse organothianthrenium salts from various precursors and their applications in organic synthesis to forge new C–C, C–H and C–heteroatom bonds by C–S bond cleavage with different mechanistic considerations.
Arynes are versatile intermediates for organic synthesis and now they can be accessed from arenes in one or two-pot sequences via aryl thianthrenium (in situ) and aryl iodonium (isolated) intermediates, respectively.
An interesting electrochemical ring-opening oxidation of aryl thianthrenium salts is accomplished without the need for chemical oxidizing reagents.
An efficient catalytic α-arylation of benzyl aryl ketones with aryl thianthrenium salts was developed using Pd/AntPhos as the catalyst.
The solvent-free mechanochemical method enables efficient synthesis of diverse organothianthrenium salts via ball-milling technique, eliminating the need for hazardous reactants, inert atmosphere, and complex reaction setups.
