“…Bands at 980 cm -1 and 919 cm -1 support the availability of cis-MoO 2 2+ core 64,65 in [1]. Occurrence of cis-MoO 2 2+ core is due to oxo abstraction 59,60 by molybdenum from THF. There is some decrease in C=O sym and asym absorptions.…”

It has been reported that molybdenum may extract oxygen from oxygen containing ligands. Oxo complexes of above bases with transition metals show numerous applications and are biologically active. So to study the biological activity of molybdenum complexes and to study oxo abstraction reactions by molybdenum, reactions of succinimide/1, 4-diaminobutane/3-methylpyridine/1, 3-diaminopropane/pyrazole/1-methylpyrrolidine with MoCl5/MoO2Cl2 have been carried out, in THF medium using equimolar/bimolar quantities of the ligand, at normal temperature. The products thus obtained are: Mo2O3Cl5(C4H5NO2)2(C4H8O)2, [1]; Mo2O2Cl2(C4H5NO2)2(C4H8O)2, [2]; MoO2Cl2(H2NCH2CH2CH2CH2NH2)2, [3]; Mo3Cl8(C6H7N)4(C4H8O)2, [4]; Mo3Cl6(C6H7N)6(C4H8O)6, [5]; MoO2Cl3(H2NCH2CH2CH2NH2)2, [6]; Mo2O4Cl4(C3H4N2)4, [7] and Mo2O6Cl8(C5H11N)4, [8]. There is oxygen abstraction by molybdenum during the reaction from the oxygen containing solvent THF. Formulations of these compounds were made and their properties were studied with FTIR(transmission mode), 1H NMR/13C NMR, microbiological studies, elemental analysis(Mo, Cl, C, H, N) and LC-MS. All preparations, separations and isolations were executed in vacuum line and inert atmosphere (dry nitrogen) to eliminate any oxidation/hydrolysis of products by air/moisture. The formulations proposed have been supported by the above characterization studies.

“…With regard to completing this picture, it can be observed that the data available in the literature relating to the chemistry of MoCl 5 with sulfoxides RR′SO are still rather sparse. MoOCl 3 (O=SPh 2 ) 2 was isolated from MoCl 5 and an excess of diphenyl sulfoxide, but no information on the destiny of the organic material possibly involved in the formation of the oxide ligand was supplied . Similarly, MoOCl 3 (DMSO) 2 was believed to form from MoCl 5 and an excess of DMSO, on the basis of insufficient characterization data …”

One‐Pot Intermolecular C–S Self‐Coupling of Dimethyl Sulfoxide Promoted by Molybdenum Pentachloride

The reactions between MoCl5 and 1–2 equiv. of a selection of sulfoxides at room temperature in dichloromethane as solvent were studied. The 1:1 molar reaction between MoCl5 and dimethyl sulfoxide (DMSO) afforded the C–S coupling product [Me2SCH2SMe][MoOCl4] (1), which was isolated in 46 % yield and characterized by analytical and spectroscopic methods and by X‐ray diffraction. MoOCl3, SMe2 and HCl were identified as side products. The reactions between MoCl5 and tetrahydrothiophene 1‐oxide, nBu2SO, MePhSO or (PhCH2)2SO yielded the corresponding sulfides and, in the cases of (PhCH2)2SO and MePhSO, also C–S activation compounds. According to DFT calculations, the unusual formation of 1 is the consequence of thermodynamically feasible Cl/O interchange between MoCl5 and DMSO, this being a prerequisite for successive C–H bond activation.
