A new two-step synthesis of N,N′-disubstituted 2,2′-biimidazoles from bisimidoyl chlorides is reported. The bisimidoyl chlorides react smoothly with (2,2-dimethoxyethyl)amine to give bisamidines that are subsequently cyclized to give the corresponding biimidazoles. acetals - biimidazole - heterocycles - cyclization - diazadiene complexes
据报道,由双亚氨基酰氯合成了N,N′-二取代的2,2′-联咪唑的新的两步合成法。双亚磺酰氯与(2,2-二甲氧基乙基)胺平稳反应,生成双am,随后将其环化,得到相应的双咪唑。 乙缩醛-联咪唑-杂环-环化-二氮二烯配合物
