Our efforts to isolate a triplet carbene as a solid so that one can “see” and keep it in a bottle have resulted in the most persistent species, namely, bis[10-(4-tert-butyl-2,6-dimethylphenyl)-9-anthryl]carbene (31). This carbene was generated by photolysis of the corresponding diazo precursor (1-N2) in toluene matrix at 77 K. The matrix was then warmed to −20°C in vacuo to evaporate the solvent to
我们努力将三重态卡宾分离为固体,以便人们可以“看到”并将其保存在瓶子中,结果产生了最持久的物质,即双 [10-(4-叔丁基-2,6-二甲基苯基) -9-蒽基]卡宾 ( 3 1 )。这种卡宾是通过在 77 K 下在甲苯基质中光解相应的重氮前体 ( 1 -N 2 ) 生成的。然后将基质在真空中加热至 -20°C 以将溶剂蒸发至干,得到黄色的卡宾3 1坚硬的。分离出的三线态卡宾被证明可以在室温下在脱气和密封的管中存活数月。
