To a xylene (40 mL) of [CpMo(CO)3]2 (0.200 g, 0.408 mmol) Was Added Dicyclopentamethylenethiuram Disulfide (0.196 g, 0.612mmol) and the Reaction Mixture Was Refluxed for 1 Hour. The Color Was Changed from Red to Red Brown. The Solvent Was Removed under Reduced Pressure and Residue Chromatographed by TLC on Silica. Elution with Cyclohexane/Dichloromethane (3:2 V/V) Gave One Band cis-[(CpMo(CO)2{S2C-N(CH2)5}] (0.167 g, 36.16%) as Red Brown Crystal from Dichloromethane/Hexane Mixture at ?4 oC. Elemental Analysis: Found C = 41.36, H = 3.99, N = 3.70, S = 16.94% and C13H15MoNO2S2 Requires C = 41.34, H = 3.98, N = 3.71, S = 16.96%. IR (υCO) in cm?1: 1857.53(s), 1949.15(s). 1H NMR (ppm): 1.54 (m, 3H), 1.63 (m, 3H), 3.56 (m, 2H), 3.79 (m, 2H), 5.41 (s, 5H).

  ABSTRACT: The reaction of [CpMo(CO)3]2 with dicyclopentamethylenethiuram disulfide in refluxing xylene resulted a novel mono nuclear complex, cis-[(CpMo(CO)2{S2C-N(CH2)5}] as red crystals in moderate yield. The compound was formed by the oxidative cleavage of metal-metal bond in [CpMo(CO)3]2 together with a reductive sulfur-sulfur bond scission in the ligand.
