Stable 1H-1,3-diazepines 7–9,10,13,14,17 and 19 are obtained, often in high yields, by photolysis of triflouoromethyl-substituted azido- or tetrazolo-pyridines in the presence of alcohols or amines; in some cases 5H-1,3-diazepines are also formed(11,21 and 23).
稳定的1H-1,3-二氮杂环(7–9,10,13,14,17和19)通常通过在
醇类或
胺类存在下,对三
氟甲基取代的
叠氮或
四唑吡啶进行光解反应获得,常常可以得到高产率;在某些情况下还会形成5H-1,3-二氮杂环(11,21和23)。
