1-Azido-3-phenalenones 5 with acyl substituents in position 2, obtained by acylation and azidation of 1-hydroxy-3-phenalenones 1, cyclized by thermolysis to give phenaleno[1,2-c]isoxazol-7-ones 9. The thermolysis conditions were studied by differential scanning calorimetry.
通过酰基化和1-羟基-3-phenalenones 1的叠氮化获得1-位置2上具有酰基取代基的1-Azido-3-phenalenones 5,通过热解将其环化,得到phenaleno [1,2-c] isoxazol-7-ones 9。通过差示扫描量热法研究了热分解条件。
