Dialkylaluminium amides iBu(2)Al(TMP) and iBu(2)Al(HMDS) can perform catalytic hydroboration of ketones with pinacolborane to form the expected boronic esters. However, repeating the same reactions stoichiometrically without a ketone leads unexpectedly to ring-opening of pinacolborane and insertion of its open chain into the Al-N(amido) bond. To date there has been limited knowledge on decomposition pathways of HBpin despite its prominent role in hydroboration chemistry. X-ray crystallography shows these mixed Al-B products [iBu(2)Al{OC(Me)(2)C(Me)(2)O}B(H)(NR2)](2) (NR2=TMP or HMDS) form dimers with an (AlO)(2) core and terminal B-N bonds. Since the bond retention (B-H) and bond breaking (B-O) in these transformations seemed surprising, DFT calculations run using M11/6-31G(d,p) gave an energy profile consistent with a sigma-bond metathesis mechanism where London dispersion interactions between iBu and (amide) Me groups play an important stabilising role in the final outcome.
