Abstract
The effect that borane and diborane have on the structure and acidity of various N-bases was analyzed using G4 ab-initio calculations. Although diborane is expected to be a stronger Lewis acid than borane, its interaction with N-bases is weaker due to the loss of one of its (3c,2e) bonds. Surprisingly, however, diborane has a significantly greater effect on the intrinsic acidity of these bases than borane. Upon deprotonation of the base, the interaction strength increases by a factor of 10 with diborane and only 3 with borane, as both the B–N and BH3···BH3 interactions are reinforced in diborane.
期刊介绍：
Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage.
Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
