    摘要:
    Ar矩阵中3-azidoquinoline 6的光解会生成3-quinolylnitrene 7,其特征是在Ar矩阵中具有电子自旋共振(ESR),UV和IR光谱。丁腈7开环至腈类叶立德19,其也由其UV和IR光谱表征。内酯19中随后的1,7-氢转移得到3-(2-异氰基苯基)酮亚胺20。1,2,3-三唑并[1,5- c ]喹喔啉26的基质光解产生4-重氮甲基喹唑啉27,然后是4-喹唑基卡宾28,其特征在于ESR和IR光谱。卡宾的进一步光解图28缓慢地产生酮亚胺20,因此表明最初形成了叶立德19。6和26的闪蒸真空热解(FVT)均以高收率提供3-氰基吲哚22,从而表明卡宾28和腈7进入相同的能量表面。3-喹啉基重氮甲烷30的基质光解产生3-喹啉基卡宾31,其在大于500 nm的光解下与N 2反应,以再生重氮化合物30。在CO的存在下30的光解会生成乙烯酮(34)。3-喹啉卡宾31在大于500 nm的光解下环化成5-氮杂2
