Synthesis and structural characterization of trithiocarbonate complexes of molybdenum and ruthenium derived from CS2 ligand

Abstract : In an effort to synthesize trithiocarbonate complexes of molybdenum and ruthenium, we carried out the reaction of CS2 with the intermediates, obtained from the reaction of [(CpML3X)-M-#], (1: Cp-# = C5Me5, M = Mo, L-1 = L-2 = L-3 = CO, X = Me; 2: Cp-# = C5H5, M = Ru, L-1 = L-2 = PPh3, X = Cl and 3: Cp-# = C5H5, M = Fe, L-1 = L-2 = CO, X = I) and [LiBH4 center dot thf]. The reactions led to formation of the trithiocarbonate complexes [Cp*Mo(CO)(2)(mu-eta(2):eta(1)-CS3)(CO)(3)MoCp*] (4) [Cp*Mo(CO)(2)(eta(2)-S2CSMe)] (5) and [Cp*Mo(-CO)(2)(eta(2)-S2CMe)] (6) in moderate yields. Treatment of [CpRu(PPh3)(2)Cl] (2) with [LiBH4 center dot thf] followed by mild pyrolysis of CS2 yielded the trithiocarbonate ruthenium complex [CpRuPPh3(eta(2)-S2CSMe)] (7). All the new compounds have been characterized by various spectroscopic techniques and the structures of compounds 4, 5 and 7 were unequivocally established by crystallographic analysis.
