Dithiocarbamates are readily S-alkylated.  Thus, methyl dimethyldithiocarbamate can be prepared by methylation of the dithiocarbamate:
:(CH)NCSNa  +  (CHO)SO   →   (CH)NC(S)SCH  +  Na[CHOSO]
Oxidation of dithiocarbamates gives the thiuram disulfide:
:2 RNCS  →  [RNC(S)S]  +  2e
Thiuram disulfides react with Grignard reagents to give esters of dithiocarbamic acid:
:[RNC(S)S]  +  RMgX   →   RNC(S)SR  +  RNCSMgX
Dithiocarbamates react with transition metal salts to give a wide variety of transition metal dithiocarbamate complexes.
