Triaryl carbenium, known as an exceptional Lewis acid, possesses a low-lying lowest unoccupied molecular orbital (LUMO) that readily accepts an electron pair, which was widely used in synthetic transformations serving as reagent or catalyst. Over the past decade, triaryl carbenium has been used as catalyst, pre-catalyst, co-catalyst and additive in organic synthesis. Moreover, triaryl carbenium as a key intermediate approached to the successful synthesis of tetra-arylmethane. In this review, the application progress of triaryl carbenium in organic synthesis in recent years is summarized, and its diverse functional roles in organic synthesis are summarized, hoping to attract widespread attention.

Key words: triaryl carbenium, catalysis, organic synthesis, metal-free
