Abstract

A sterically congested NHC–AlMe₃ Lewis adduct (NHC = 1,3-di-tert-butylimidazol-2-ylidene) was found to either isomerize to an “abnormal” NHC–AlMe₃ species or to be involved in the deprotonation of AlMe₃ to form the corresponding imidazolium species along with an AlMe₃-stabilized methylene aluminium anion.
