By employing reusable nanocobalt oxides as the catalysts, a site-specific oxidative C-H chalcogenation of (hetero)aryl-fused cyclic amines with various thiols and diselenides is presented for the first time. The reaction proceeds selectively at the sites of the (hetero)aryl rings para to the N atom, and enables access to a wide array of chalcogenyl N-heteroarenes. The merits of the transformation involve high step- and atom-efficiency, excellent substrate and functional compatibility, operational simplicity, and the use of a naturally abundant Co/O2 system. The present work has offered a fundamental basis for the selective synthesis of functional N-heteroarenes from readily available feedstocks.

Disclosed is an efficient and widely-applicable method for commercially producing a thioether compound or a thiol compound which is useful as a pharmaceutical product or a production intermediate of a pharmaceutical product. Specifically disclosed is a method for producing a thioether compound represented by the general formula [I] below or a salt thereof. This method is characterized in that a compound represented by the following general formula [III]: [III] (wherein X represents a bromine atom, a chlorine atom or a trifluoromethylsulfonyloxy group, and ring A represents an aryl group or a heteroaryl ring group) or a salt thereof is reacted with a thiol compound represented by the following general formula [II]: [II] or a salt thereof in the presence of a palladium compound such as Pd2(dba)3, a base such as i-Pr2NEt and a phosphorus compound represented by the following formula [AA].
