The reaction of phosphorus pentachloride with some 3:5-disubstituted-4-nitrosopyrazoles (dimethyl, diphenyl, methyl phenyl and phenyl carbomethoxy) has been investigated. Formation of a new class of compounds, 1-chloro-4-cyano-2:3-diazabuta-1:3-dienes, is described. By treatment with ammonia and subsequent alkali-induced cyclisation these substances are converted into 5-amino-as-triazines and reactions
研究了五氯化磷与一些3:5-二取代的4-亚硝基吡唑(二甲基,二苯基,甲基苯基和苯基碳甲氧基)的反应。描述了新型化合物1-氯-4-氰基-2:3-二氮杂丁-1:3-二烯的形成。通过与氨和随后碱诱导的环化处理,这些物质被转化成5-氨基作为-triazines和后者的反应进行了研究。
