A new method of the synthesis of 3-(2,2-dimethylhydrazono)-5-R-1,1,2,2-tetracarbonitriles via oxidation of 3-(2,2-dimethylhydrazino)-5-R-1,1,2,2- tetracarbonitriles with diluted nitric acid was developed. High reactivity of 3-(2,2-dimethylhydrazono)-5-R-1,1,2,2-tetracarbonitriles caused by the presence of ethyl-1,1,2,2-tetracarbonitrile and N,N-dimethylhydrazone moieties allowed obtaining 2-methyl-5-R-3
通过氧化3-(2,2-二甲基肼基)-5-R-1,1合成3-(2,2-二甲基肼基)-5-R-1,1,2,2-四甲腈的新方法用稀硝酸开发了1,2,2-四腈。由于乙基-1,1,2,2-四甲腈和N,N-二甲基hydr部分的存在而引起的3-(2,2-二甲基hydr基)-5-R-1,1,2,2-四腈的高反应活性获得2-甲基5-R-3,4-二氢-2 Н环戊〔ë ] -1,2,4-三嗪6,6,7,7-tetracarbonitriles,3-氨基-4-(2,2-二甲基亚肼基)-6-甲基-1,3α,4,5,6,6α-六氢环戊[ c ]吡咯-3α,6α-二腈和3-(2,2-二甲基肼基)-5-甲基环戊-2-烯-1 ,1,2-三碳腈。
