Oxidative addition of the electron-rich tetra-methoxy-dibenzo-1,2,5,6-tetrathiocine [(MeO) 2 C 6 H 2 S 2 ] 2 to zero-valent group 10 transition metal complexes in the presence of diphenylphosphinoethane (dppe) affords the corresponding dithiolate complexes, [(DMOBD)M(dppe)] (DMOBD = dimethoxybenzenedithiolato, (MeO) 2 C 6 H 2 S 2 2− ; M = Ni, Pd, Pt) in high yield which were characterized by single crystal X-ray diffraction. Whereas the Pd and Pt complexes exhibit two quasi-reversible 1e − oxidation processes, the nickel species undergoes a quasi-reversible 1e − reduction. The oxidative addition of tetrathiocines to zero valent group 10 metals under microwave irradiation affords a convenient high-yielding one-pot synthesis of Ni, Pd and Pt dithiolate complexes.
