    • A method of the invention industrially produces heterocyclic mercapto compounds useful as raw materials or intermediates in the synthesis of medicaments or pesticides, or as permanent wave agent, with a high yield and high productivity using easily available starting materials. A heterocyclic mercapto compound represented by Formula (1) (wherein X represents any structure of —O—, —S—, —NH—, and —NR1—; R1 represents any of an alkyl group, alkoxy group and alkoxyalkyl group each having 1 to 6 carbon atoms; Y represents an oxygen atom, a sulfur atom or —NR2—; R2 represents a hydrogen atom or alkyl group having 1 to 6 carbon atoms; and Z1 represents a divalent organic residue having at least one mercapto group) is produced by reacting a metal sulfide or a metal hydrosulfide with a compound represented by Formula (2) (wherein X and Y are as defined in Formula (1); and Z2 represents a divalent organic residue having at least one halogen group) in the presence of a solvent at a pH of 7.0 to 11.0.
    • 本发明的工业生产方法是使用容易获得的起始原料工业生产用作合成药物或农药的原料或中间体的杂环巯基化合物,或作为永久挥发剂,以高产率和高生产率。 由式(1)表示的杂环巯基化合物(其中X表示-O - , - S - , - NH-和-NR 1 - 的任何结构; R 1表示任何烷基,烷氧基和烷氧基烷基, 6个碳原子; Y表示氧原子,硫原子或-NR 2 - ; R 2表示氢原子或碳原子数1〜6的烷基,Z1表示具有至少一个巯基的二价有机残基) 通过使金属硫化物或金属氢硫化物与式(2)表示的化合物反应(其中X和Y如式(1)中所定义; Z 2表示具有至少一个卤素基团的二价有机残基) pH 7.0〜11.0的溶剂。
