Thiiranes such as 2-methylthiirane and epithiocyclohexane, catalyzed by rhenium complexes, are useful reagents for sulfurization of phosphorus(iii) compounds (Equation (32) Table 3) <1997TL7701>. Mild reaction conditions and a short reaction time make this method of sulfurization of phosphorus(ni) compounds most interesting. Possible mechanisms for the rhenium-catalyzed sulfurization of phosphorus(lll) compounds are outlined in Scheme 38. 

The latter case has been demonstrated with the reaction of [ReCl3(PPh3)2(CH3CN)] with a large excess of sodium diethyldithiocarbamate which results in sulfur abstraction and in the formation of a mixed phosphine/diethyldithiocarbamato/r/ -thiocarbamoyl complex. For the molecular structure of this compound see formula (225) which represents that of the corresponding rhe-nium(IV) cation which is formed by oxidation of the primarily formed Re complex and contains one rhenium-carbon bond. The formation of thiocarbamoyl compounds seems to be an essential... 

Pseudo-allyl compounds are formed from reactions of [Re(CO)2(PPh3)2(OCHNC6H4-4-Me)] with excess of PhNCO or PhNCS. Whereas carbamate compounds are formed in the former case, a mixture of monothio- and dithiocarbamate compounds is obtained with the sulfur analogue. The formation of the latter complex proceeds via the intermediate formation of the first. The related compounds show similar structural features with distorted octahedral rhenium atoms and... 

Manganese and rhenium carbonyl compounds, such as 8, react with AgAsFe in liquid SO2 to give the carbonyl complexes 9 incorporating the sulfur dioxide. ...
