[(Cp‘Mo(μ-S))2(S2CH2)]2(BF4)2 (1: Cp‘ = C5H5 (1a), C5H4Me (1b)), in which two dinuclear complexes are joined by a sulfur−sulfur bond, reacts with the electron-rich nitrogen heterocycles pyrroles and indoles at room temperature. The reactions involve heterolytic scission of the disulfide bond by the nucleophiles followed by proton transfer, and the products are [(Cp‘Mo)2(S2CH2)(μ-S)(μ-SH)]BF4 (2) and
