In the case of BF3 and CaO you might predict you'd get a product like Ca[BF3O] -- the more canonical example is a borane like BH3 (a Lewis acid) reacting with an amine like ammonia (a Lewis base) to form the Lewis acid-base adduct amine-borane, H3N-BH3.
12 paź 2016 · Two ionic equilibrium models were proposed to simulate the hydrolysis equilibrium of BF 3 and tested by special acid-base titration technique. The most accurate ion equilibrium constants were determined.
23 lip 1999 · In this Letter, we report ab initio calculations on the clusters, BF 3 + (HF) 1–7. The underlying objective of this study is to understand the important superacid system HF/BF 3 by focusing on the role of the solvent.
The thermodynamics solvolysis constant of the BF 4 − ion in liquid anhydrous hydrogen fluoride was determined to be 7·7 × 10 −3 by a method of solubility measurements. From the extensive solvolysis of its salt, it was concluded, therefore, the BF 3 was not a strong acid in liquid HF.
29 lis 2015 · If BF 3 stripped an H atom off a water molecule, it would technically leave OH-in the solution, and actually raise the pH instead. BF 3 is a Lewis acid. Why would it raise the pH?
1 sty 1976 · PF 5 (PF 5 + F − ⇌ PF 6−; log KPF6− = 3·85) is a very weak fluoride ion acceptor in AHF. BF 3 (log KBF4 = 7·26), NbF 5 (log KNbF6 = 6·88) and TaF 5 (log KTaF6 = 8·88) are fluoride ion acceptors of moderate strength, and AsF 6 (log KAsF6 = 16·9) is a quite strong fluoride ion acceptor.
The results essentially showed that the enthalpy of BF 3 adduct formation in DCM solution was clearly influenced by specific interactions, with DCM acting as hydrogen-bonding donor (HBD) molecule in two ways: base/DCM and adduct/DCM, confirming that specific solvation is an important contribution to experimentally determined Lewis basicity ...
