Metal triflates attracted a large interest as catalysts in the past three decades especially due to the Lewis acid properties exhibited by these compounds and the variety of the functional group transformations. This chapter proposes an overview presenting the catalytic performances of triflates both as molecular compounds and as triflates dispersed in different solid matrices. In the first part the performances of molecular triflates in organic reactions carried out in the presence of water or water as solvent considering both water-sensitive and -insensitive metals are discussed. Then, the importance of materials incorporating triflates is demonstrated for catalysts obtained via immobilization of the metal triflates on various supports including organic polymers or inorganic materials. Nanomagnetic particles ensuring the magnetic recyclability of the resulted heterogeneous Lewis acids have been investigated as well. The nature of the acid sites in metal triflates and triflimidates is analyzed based on the results provided by the different characterization techniques. Also, the synthesis of these materials and the adequation of the support architecture are presented in a close relation with the catalytic reactions and the characterization of the materials.
