The reaction of [CpMn(CO)2C(O)Ph]-Li+ with an equimolar amount of sulfur gives the paramagnetic thiocarboxylate complex CpMn(CO)2SC(O)Ph (1), which is converted on treatment with sulfur into the known binuclear diamagnetic complex [CpMn(CO)2] 2(μ-S2) (2). Treatment of [CpMn(CO)2C(O)Ph] -Li+ with elemental selenium under similar conditions gives the dimer [CpMn(CO)2]2(μ-Se2) (3). The reduction of 2 and 3 by sodium borohydride followed by the reaction with methyl iodide affords the mononuclear complex CpMn(CO)2SMe2 (4) and binuclear complexes [CpMn(CO)2]2(μ-XMe2) (X = S (5), Se (6)). On heating in hexane, 4 is converted into 5. The structures of complexes 1 and 3-6 were characterized by X-ray diffraction. The EPR spectrum of 1, the electrochemical behavior of 2 and 3, and the thermal decomposition of 2, 3, 5, and 6 were investigated.
