Reaction of 2,4-dinitrophenoxychlorodiazirine (13) with chloride ions affords dichlorodiazirine (4). Photolysis of 4 generates dichlorocarbene. In laser flash photolysis (LFP) experiments, CCl2 forms chromophoric ylides or oxides with pyridine, 2-picoline, thioanisole, and oxygen. Spectroscopic and computational studies of the ylides are reported. The UV spectrum of CCl2 in solution, however, is not
2,4-二硝基苯氧基氯二氮嗪 (13) 与氯离子反应得到二氯二氮嗪 (4)。4 的光解产生二氯卡宾。在激光闪光光解 (LFP) 实验中,CCl2 与吡啶、2-甲基吡啶、苯硫醚和氧形成发色叶立德或氧化物。报道了叶立德的光谱和计算研究。然而,没有观察到溶液中 CCl2 的紫外光谱。CCl2 似乎有可能被氧气迅速捕获以提供发色的二氯卡宾羰基氧化物。我们对这个过程进行了理论分析。
