ABSTRACT:
A new and improved process for synthesizing thiolcarbamates, which are known herbicides, is disclosed. The thiolcarbamates are obtained in good yields, and without involving the use of highly poisonous, polluting, or hard-to-find reactants, by reacting dithiocarbamates with dimethylsulphoxide in the presence of a catalytic amount of iodine and at temperatures comprised between 50.degree. and 200.degree. C.
