氯化N-[5′-(3′-甲硫基-6′-甲基)-1,2,4-三嗪基]-吡啶嗡盐(Ⅰ)在吡啶中于室温通入硫化氢,或与用硫化氢饱和的硫氢化钠溶液反应,都得到了3-甲硫基-5-巯基-6-甲基-1,2,4-三嗪(Ⅱ),熔点178—179℃;于较高温度通入硫化氢进行反应,得3,5-二巯基-6-甲基-1,2,4-三嗪,熔点217—218℃。二者均可于氢氧化钠溶液中与碘甲烷作用,得到3,5-二甲硫基-6-甲基-1,2,4-三嗪,熔点78—79℃。化合物(Ⅰ)在吡啶水溶液中与邻甲苯酚、苯酚、邻
Chloride N- [5 ’- (3’-Methylthio-6’-methyl) -1,2,4-triazinyl] -pyridinium Salt (I) Hydrogen sulfide was introduced into pyridine at room temperature, Or with sodium hydrosulfide saturated with hydrogen sulphide to afford 3-methylthio-5-mercapto-6-methyl-1,2,4-triazine (II), m.p. 178-179 ° C; Hydrogen sulfide was introduced into the reactor at a higher temperature to obtain 3,5-dimercapto-6-methyl-1,2,4-triazine, melting at 217-218 ° C. Both of them can react with methyl iodide in sodium hydroxide solution to obtain 3,5-dimethylthio-6-methyl-1,2,4-triazine, melting at 78-79 ° C. Compound (I) is o-cresol, phenol, o-cresol in pyridine aqueous solution
