An Aluminum-Based Lewis Superacid and Its Weakly Coordinating Anions Derived from an Organotellurium Ligand.

ABSTRACT: Lewis acids and their related weakly coordinating anions (WCAs) are central species in chemistry, and tuning their properties toward different purposes is still a challenging field of research. In this work, the properties of the Lewis acid Al-(OTe^R)₃ have been investigated using the advantages of the OTeF₃(C₆F₅)₂ ligand (OTe^R). Its Lewis acidity was evaluated by means of fluoride ion affinity (FIA) calculations, indicating that it is a Lewis superacid. Complementary analysis using the Gutmann-Beckett method by the synthesis of the Al-(OTe^R)₃·OPEt₃ adduct rendered similar results, yet for the heavier Ga species this adduct formation was not possible, as only GaEt-(OTe^R)<
