Highly Lewis acidic cationic alkaline earth metal complexes.

Abstract

Cationic Lewis base-free β-diketiminate (BDI) complexes of Mg and Ca have been isolated as their B(C6F5)4- salts. The cation (BDI)Mg+ shows an extraordinarily strong Lewis acidity that can compete with strong Lewis acids like B(C6F5)3 and (BDI)AlMe+. Its highly electrophilic nature is exemplified by isolation of an 3-hexyne adduct.
