Analogous reactivity of MoS42– and WSe42–: preparation of WSe2(Bui2NCS2)3 by an induced internal redox reaction

Addition of tetreaalkylthiuram disulfides R2NC(S)S–SC(S)NR2(R = Et and Bui) to WSe42– yields the new complexes WvSe2(R2NCS2)3, revealing that WSe42– undergoes induced internal electron transfer similar to that of MoS42–, but different from the reactivity of WS42–, as predicted by comparison of the lowest energy charge transfer transitions of the reactants.
