The hydrogenation reactions of diphenylcarbene 1, fluorenylidene 2, and dibenzocycloheptadienylidene 3 were investigated in solid H2 and D2 matrices and in H2‐ and D2‐doped argon matrices at cryogenic temperatures. The reactivity of the carbenes towards H2 increases in the order 1<3<2. Whereas 1 is stable in solid H2, 2 and 3 react fast under the same conditions via quantum chemical tunneling. In D2
diphenylcarbene的氢化反应1,芴2和dibenzocycloheptadienylidene 3在固体1 H进行了调查2和d 2矩阵和H中2和d - 2点在低温下掺杂氩矩阵。卡宾对H 2的反应性以1 < 3 < 2的顺序增加。而1是稳定的固体。1 H 2,2和3的反应快速通过量子隧穿化学相同的条件下。在D 2中都1和3稳定,而2缓慢反应。根据不同的卡宾稳定能,合理化了三种卡宾的不同反应性。
