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.

The compound is formed by oxidative cleavage of Mo-Mo triple bond together with a reductive S-S bond scission in tetramethylthiuram disulfide ligand (Scheme 1)
We carried out the analogous reaction of dicyclopentamethylenethiuram disulfide with [CpMo(CO)3]2 and reported the formation of a mononuclear cyclopentadienyl molybdenum dicarbonyl complex, cis-[(CpMo(CO)2{S2C-N(CH2)5}]
