  • Carbene-Based Lewis Pairs for Hydrogen Activation

    A series of Lewis acid–base pairs containing sterically demanding carbenes were investigated for hydrogen activation that could potentially be reversible for use in hydrogen storage applications. When electron-rich boranes are employed as electrophiles, the imidazolium cation is reduced to a 2H-imidazoline (aminal). The aminals were synthesized independently by reduction of imidazolium cations with strong reducing agents. Carbocations were also found to act as electrophiles for hydrogen activation. Preliminary results revealed that it is possible to reduce an alcohol to an alkane using hydrogen gas as a reducing agent in these systems. Finally, it was demonstrated that a transition metal can be used as an electrophile to activate hydrogen through heterolytic cleavage.

    我们研究了一系列路易斯酸-碱对,其中含有对立体要求较高的烯碳化合物,这些化合物具有潜在的可逆性,可用于氢气储存。当使用富电子硼烷作为亲电体时,咪唑阳离子会被还原成 2H-咪唑啉(基)。通过用强还原剂还原咪唑阳离子,可独立合成氨基化合物。研究还发现,碳化物可作为氢活化的亲电体。初步结果表明,在这些体系中使用氢气作为还原剂,可以将醇还原成烷烃。最后,还证明了过渡属可以作为亲电体,通过异解裂解激活氢。

    bis(diisopropylphosphino)ethane) was also capable of catalyzing the hydrogenolysis of biphenylene under an atmosphere of H2 at 120 °C. The rate of hydrogenolysis increases as the concentration of biphenylene, H2, and (dippe)PtH2 increases. These observations are consistent with the C−C bond activation of biphenylene occurring via (dippe)PtH2, not [(dippe)Pt0]. The rate of catalytic hydrogenolysis was not affected
