PROCESS FOR PRODUCING THIOLCARBAMATS

摘要

A thiolcarbamate having the formula (V) wherein R1 and R2 are the same or different and respectively represent an alkyl, alkoxy, alkenyl, cycloalkyl, hydroxyalkyl, phenyl or benzyl group and R1 and R2 can form a ring by binding each other with or without oxygen atom; and R3 represents a lower alkyl or benzyl group or a substituted benzyl group having one or two substituent of halogen atom, alkyl, alkoxy, alkylthio, nitro, or cyano group, which comprises reacting carbonyl sulfide with a sec-amine having the formula (I) wherein R1 and R2 are defined above, in an aqueous medium and then reacting a halogenated hydrocarbon having the formula X-R3 (IV) wherein R3 is defined above and X represents a halogen atom, in an aqueous medium.
