    • 4 is 464 kJ/mol, but the B3P86/6-311 + +G(d,p) prediction is 423.5 kJ/mol which is underestimated by over 40 kJ/mol. In comparison, the G3B3 prediction is 461.7 kJ/mol and the CBS-QB3 prediction is 469.1 kJ/mol. Thus one must always be careful about using the cheap DFT methods in BDE calculations.
