Methyl dimethyldithiocarbamate

Methyl dimethyldithiocarbamate is the organosulfur compound with the formula (CH3)2NC(S)SCH3. It is the one of simplest dithiocarbamic esters. It is a white volatile solid that is poorly soluble in water but soluble in many organic solvents. It was once used as a pesticide.

Methyl dimethyldithiocarbamate can be prepared by methylation of salts of dimethyldithiocarbamate:
 * (CH3)2NCS2Na +  (CH3O)2SO2   →   (CH3)2NC(S)SCH3  +  Na[CH3OSO3]

It can also be prepared by the reaction of a tetramethylthiuram disulfide with methyl Grignard reagents:
 * [(CH3)2NC(S)S]2 +  CH3MgBr   →   (CH3)2NC(S)SCH3  +  (CH3)2NCS2MgBr
