Exploring the Limits of π‐Acid Catalysis Using Strongly Electrophilic Main Group Metal Complexes: The Case of Zinc and Aluminium

Résumé

The catalytic activity of cationic NHC-Zn(II) and NHC-Al(III) complexes in reactions that require the electrophilic activation of soft CC  bonds has been studied. The former proved able to act as a soft -Lewis acid in a variety of transformations. The benefit of the bulky IPr NHC ligand was demonstrated by comparison with simple ZnX2 salts. The tested NHC-Al(III) catalyst is not able to activate CC  bonds but simple AlX2 + ions were found potent in some cases.
