Reactions of MoCl5 and MoO2Cl2 with 4-Phenylimidazole-2-Thiol and 2-Thiazoline-2-Thiol

Abstract

Reactions of MoCl5/MoO2Cl2 with 4-phenylimidazole-2-thiol/2-thiazoline-2-thiol in CH3CNsolvent in 1:1/1:2 molar ratios have been carried out at room temperature. Products obtained MoCl3(C9H7N2S)(CH3CN), [1];MoCl2(C9H7N2S)(CH3CN), [2]; Mo2OCl4(C9H8N2S)2, [3] and Mo4O2Cl12(C9H7N2S)4, [4]; MoO2Cl3(C3H5NS2)2, [5] and Mo2O4Cl3(C3H5NS2)2, [6] have been analyzed and characterizedby elemental analysis, FTIR, 1H NMR and LC-MS techniques. Compounds being moisture and air sensitive, these have been prepared in inert atmosphere using vacuum line and liquid nitrogen cooled traps. Fragments obtained in LC-MS spectra support the formulae derived.

Reactions of MoO2Cl2 and MoOCl4 with 2-Mercaptopyridine, 4-Phenylimidazole-2-thiol and 6-Mercaptopurine Monohydrate

“…MoO 2 Cl 2 and MoOCl 4 are known to react with a variety of ligands. The author earlier investigated [31][32][33][34][35][36][37] reactions of MoO 2 Cl 2 with various diaminoalkanes, alkanediols, amides, imides, thiols and aromatic azoles.…”

“…Absorption at 3137 cm -1 in[1] refers to N-H stretching of 4-phenylimidazole-2-thiol 37,[41][42][43] (Table 2). There is no υ(S-H) in the range 2551-2602 cm -1 of[1] indicating S-H group is not present it.…”

“…Mo=O stretching [45][46][47] was observed at 986 cm -1 . There is thiol-thione tautomerism in imidazole-2-thiones 37,43 . Mo=O stretching shows downward shift owing to S→Mo coordination 37,48 of 4-phenylimidazole-2-thiol.…”
