Four isomeric azulenylcarbenes were synthesized in argon matrices by photolysis of the corresponding diazo precursors, and the photochemistry of these carbenes was studied. The carbenes and their rearranged products were characterized by IR, UV/Vis, and EPR spectroscopy, and the experimental data were compared to results from DFT calculations. While 2‐, 5‐ and 6‐azulenylcarbene show triplet ground
通过光解相应的重氮前体,在氩气基质中合成了四种异构的氮杂烯基卡宾,并研究了这些卡宾的光化学性质。通过IR,UV / Vis和EPR光谱表征了卡宾及其重排产物,并将实验数据与DFT计算的结果进行了比较。与理论预测相符,2-,5-和6-氮杂烯基卡宾显示出三重态基态,而1-氮杂烯基卡宾显示出单重态基态。氮烯基卡宾的重排使得可以访问许多不寻常的C 11 H 8异构体,例如其他碳烯和应变的烯。
