Abstract

Lanthanide salts are often employed as catalysts in organic synthesis, 11 mainly due to their low toxicity, affordability, stability, and ease of handling. 12 In pursuit of our interest in developing new methods for reactions catalyzed by cerium(III) salts 13 and taking into account that lanthanide triflates have been reported as promoters of Friedel–Crafts reactions, 14 we decided to study the direct alkylation of aromatic compounds with propargylic alcohols under Ce(OTf) 3 ...
