Metal- And solvent-free synthesis of aniline- And phenol-based triarylmethanes: Via Br?nsted acidic ionic liquid catalyzed Friedel-Crafts reaction

A beneficial, scalable and efficient methodology for the synthesis of aniline-based triarylmethanes has been established through the double Friedel-Crafts reaction of commercial aldehydes and primary, secondary or tertiary anilines using Br?nsted acidic ionic liquid as a powerful catalyst, namely [bsmim][NTf2]. This protocol was successfully performed under metal- and solvent-free conditions with a broad range of substrates, giving the corresponding aniline-based triarylmethane products in good to excellent yields (up to 99%). In addition, alternative aromatic nucleophiles such as phenols and electron-rich arenes were also studied using this useful approach to achieve a diversity of triarylmethane derivatives in high to excellent yields.

Heterobimetallic Ir-Sn catalysis: Aza-Friedel-Crafts reaction of N-sulfonyl aldimines

The heterobimetallic complex [Ir(COD)(SnCl3)Cl(μ-Cl)] 2 catalyzes the aza-Friedel-Crafts reaction of 1,3,5- trimethoxybenzene, as well as substituted indoles with N-sulfonyl aldimines leading to the formation of diarylamines and triarylmethanes in good yields. The symmetrical triarylmethanes were also obtained from diarylamines and suitable nucleophiles via simultaneous cleavage of sp3 C-N bond and elimination of 1,3,5-trimethoxybenzene.
