氢化物转移反应在有机合成、光电催化、氢活化等许多过程中都有重要的应用，因此氢化物的性质具有重要的意义。在此，在气相中检查一系列硅烷的动力学氢化度。迄今为止，这些反应中的大多数还没有在真空中进行过研究，并提供了有价值的数据，可以与凝相水合作用进行比较，以揭示溶剂的影响。实验和计算都用于深入了解机理和反应性。从更广泛的意义上说，这些研究也代表了在没有溶剂的情况下系统地理解亲核性和亲电性的第一步。
Hydricity is of great import as hydride transfer reactions are prominent in many processes, including organic synthesis, photoelectrocatalysis, and hydrogen activation. Herein, the kinetic hydricity of a series of silanes is examined in the gas phase. Most of these reactions have not heretofore been studiedin vacuoand provide valuable data that can be compared to condensed-phase hydricity, to reveal the effects of solvent. Both experiments and computations are used to gain insight into mechanism and reactivity. In a broader sense, these studies also represent a first step toward systematically understanding nucleophilicity and electrophilicity in the absence of a solvent.
