The synthesis of alkylthiocarbamates from an alkali metal salt of thiocarbamic acid and halogenohydrocarbons in an aqueous medium has been investigated with exposure to ultrasound and without such exposure but under conditions of vigorous stirring.The intensifying effect of ultrasound on the synthesis thiocarbamates has been demonstrated.

The invention relates to a new and advantageous process for the preparation of substituted S-alkyl thiocarbamates having the general formula (I), EQU1 wherein R1 stands for a C1-4 alkyl group, R2 stands for a C1-4 alkyl or cyclohexyl group, or R1 and R2 may form together a C4-6 polymethylene group, and R3 stands for a C2-3 alkyl group. In accordance with the invention the substituted O-alkyl thiocarbamates of the general formula (II), EQU2 wherein R1, R2 and R3 each have the same meanings as defined above, are subjected to isomerization by heating them at a temperature of 130° to 180°C in the presence of dimethyl sulfate or diethyl sulfate to yield the appropriate S-alkyl esters.
