| Abstract
| - The calculated proton affinities of four borane−amines using Gaussian-2 theory have been found to becomparable to conventional bases such as water, methanol, and ammonia. On the other hand the structure ofprotonated borane−ammonia, [HBH3−NH3]+, is found to be drastically different from that of protonatedammonia, [HNH3]+, and can appropriately be described as a η2-H2 complex with [BH2−NH3]+ molecularcation. Further, the proton affinities of borane−amines are related to the ease of H2 elimination.
