The reactivity of the free aluminylene [N]-Al (1) ([N]=1,8-bis(3,5-di-tert-butylphenyl)-3,6-di-tert-butylcarbazolyl) towards boron Lewis acids is investigated. A facile oxidative addition reaction of 1 with PhBOBPh furnishes an exceedingly scarce example of the free alumaborane [N]-Al(BPh)(OBPh) (2) with an Al−B electron-sharing bond. By contrast, complexation of 1 with B(CF) and HB(CF) gives rise to the corresponding Lewis adducts [N]-Al→B(CF) (3) and [N]-Al→BH(CF) (4), respectively, with an Al→B dative bond. Crystallization of 4 in EtO produces the adduct [N]-Al(EtO)→BH(CF) (5). Quantum chemical calculations are carried out to understand the formation of 2 as well as the bonding situation of 3 and 5.
