reaction of furan-2,3-diones with S-methylisothiosemicarbazide hydroiodide yielded novel 1,2,4-triazine-5(4H)-ones, and reaction of furan-2,3-diones with diaminomaleonitrile led to the formation of pyrazine-2,3-dicarbonitrile derivatives, and the hydrolysis of these products led to the formation of more new pyrazine-2,3-dicarbonitrile derivatives. These compounds are potential herbicides and pesticides
呋喃-2,3-二酮与S-甲基异硫代氨基脲氢碘化物的反应生成了新的1,2,4-三嗪-5(4 H)-酮,呋喃-2,3-二酮与二氨基马腈的反应导致形成吡嗪-2,3-二碳腈衍生物,以及这些产物的水解导致形成更多新的吡嗪-2,3-二碳腈衍生物。这些化合物是潜在的除草剂和杀虫剂。
