Abstract
PURPOSE: To prepare an N-substituted thiolcarbamate compound useful as a herbicide, insecticide, pesticide, etc., in high purity and yield, by using finely divided alkali hydroxide as an alkali hydroxide.
CONSTITUTION: An amine (e.g. primary or secondary amine having alkyl or alkenyl group) is reacted with carbonyl sulfide and finely divided alkali hydroxide in the presence of an aprotic polar solvent (e.g. pentane) to obtain a stable and highly reactive N-substituted thiolcarbamic acid alkali metal salt, which is made to react with an alkyl halide in an aprotic polar solvent to affort the objective N-substituted thiolcarbamate compound.
EFFECT: Care to the reaction temperature is not necessary. The necessary treatment after the reaction is simple, e.g. filtration and concentration. The load to the waste water treatment facilities can be reduced.
