Webalkoxy-NHC metallated product is indeed obtained with Al(iBu) 3. In contrast, the sterically hindered [Al(iBu)(OAr) 2] (OAr = 2,6-di-tertbutyl-4-methylphenoxy) displays reactivity at the carbene and affords an imidazolium-aluminate zwitterion. The non-innocence of the Al-NHC motif is further highlighted by the heterolytic cleavage
