“…In earlier studies of (CpMo(μ-S) 2 S 2 CH 2 , we found that protic acid played a role in many of the reactions at the sulfido ligands, which resulted in multiple bond reductions or in carbon−heteroatom bond cleavage. − It has not been possible to extend this type of chemistry to aqueous solvents because the carboxylate-substituted complexes are not soluble in acidic solution. Rapid protonation of the carboxylate groups leads to neutral dimers, which are soluble only in DMSO or DMF solutions.…”

Dinuclear μ-Sulfido Complexes of Molybdenum with (Dimethylamino)ethyl-Substituted Cyclopentadienyl Ligands

The cyclopentadienyl ligand with the (dimethylamino)ethyl substituent has been used in the synthesis of the dinuclear μ-sulfido molybdenum complex (Me2NCH2CH2CpMo(μ-S))2S2CH2, 4, and related derivatives. Complex 4 has been isolated and characterized by spectroscopic methods as well as by an X-ray diffraction study. The structure confirms a bis(μ-sulfido) derivative in which the dimethylamino substitutents of the Cp ligands are directed away from the Mo2S4 core. Protonation of 4 produces the dicationic complex with dimethylammonium substitutents, which is soluble in water and other polar solvents. Reaction of 4 with [CuOTf]2·C6H6 leads to the formation of a copper adduct [(Me2NCH2CH2CpMo(μ-S))2Cu(S2CH2)]OTF, 6a. NMR studies of 6a in CD2Cl2 suggest that the copper ion is stabilized by two sulfido ligands and by weakly coordinated dimethylamino groups.

“…However, if the reaction was carried out at 55 °C, the formation of NH 3 was not observed. This is probably because 2a reacts much more quickly with THF than with 1b at that temperature to give a cationic complex with a 4-hydroxybutanethiolate ligand . In all cases, only a trace amount of NH 2 NH 2 was observed.…”
