Calculational study of the protonation of BXH2 and BX2H (X = F and Cl). Structures of BXH3+ and BX2H2+ and their dihydrogen complexes BXH5+ and BX2H4+
Ab initio calculations on monoprotonated BFH2 indicate that the B-H protonated la is 9.7 kcal/mol more stable than the F-protonated Ib. Thus the bonded electron pair of the B-H bond is a better donor than the nonbonded fluorine electron pair in BFH2.
