Compounds of the formula ##STR1## and alkali metal or alkaline earth metal salts thereof, wherein R.sup.1 and R.sup.2 are the same or different and each is hydrogen, alkyl, alkoxy, haloalkyl, polyhaloalkyl, haloalkoxy, polyhaloalkoxy or halo; R.sup.3 is methyl, hydroxy or amino; are produced by treating the corresponding 3-cyanoquinoxaline-di-N-oxide of the formula ##STR2## wherein R.sup.1, R.sup.2 and R.sup.3 are as above defined, with hydrogen sulfide or an alkali metal or alkaline earth metal salt thereof. When a salt of hydrogen sulfide is used, the resulting mercaptide product may be converted to the corresponding mercaptan by treatment with an acid to produce the corresponding 2-mercaptoquinoxaline-di-N-oxide.
公式为##STR1##的化合物及其碱金属或碱土金属盐,其中R.sup.1和R.sup.2相同或不同,每个都是氢、烷基、烷氧基、卤代烷基、多卤代烷基、卤代烷氧基、多卤代烷氧基或卤代;R.sup.3是甲基、羟基或氨基;通过用氢硫化物或其碱金属或碱土金属盐处理相应的公式为##STR2##的3-氰基喹喙啉二-N-氧化物产生,其中R.sup.1、R.sup.2和R.sup.3如上定义;当使用硫化氢盐时,所得的巯基产物可以通过用酸处理转化为相应的巯基喹喙啉二-N-氧化物。
