3-Azido-1-phenalenones 4 with aryl- or hetarylsubstituents in position 2 cyclized by thermolysis to give naphtho[8,1-ab]carbazolones 5 or naphtho[8,1-ab]-8a-azonia-9-λ2-azafluorenones 7. Reduction of the azides 4 gave the corresponding amino derivatives 9. The thermolysis conditions were studied by differential scanning calorimetry.
与芳基-或hetarylsubstituents 3-叠氮基-1- phenalenones 4在位置2由环化的热解,得到萘并[8,1- AB ] carbazolones 5或萘并[8,1- AB ] -8A氮鎓- 9-λ 2 -氮杂芴酮7.叠氮化物4的还原得到相应的氨基衍生物9.通过差示扫描量热法研究了热解条件。
