boron, Balkali metalsAn ab initio theoretical study of BF 3 , BCl 3 and BBr 3 has been carried out at different levels of calculation in order to interpret the experimental Lewis acidity scale of these molecules. The results obtained show that the increase in acidity when going from BF 3 ...
The Lewis acidity scale of boron trihalides BX3 (X=F, C1, Br, I) and character of the boron-halogen bonds have been studied by means of DV-Xm approach. Present results show that the acid strength of boron trihalides increases in the order BF3...
The results obtained show that the increase in acidity when going from BF3 to BBr3 can be understood in terms of the electron affinity and of the nature of the boron-halogen bond.doi:10.1016/0166-1280(91)87008-aVicen? BranchadellAntonio Oliva...

That's strainful! The stability of Lewis pairs involving boron trihalides and ammonia is driven by the energy required to deform the Lewis acids upon complexation, while the stability of Lewis pairs between borane and nitrogen trihalides is determined by the strength of orbital interactions.doi:...
