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.

Synthesis of symmetric triarylmethane derivatives catalyzed by AIL ionic liquid

Abstract: An efficient, eco-friendly ionic liquid was described for the synthesis of symmetric triarylmethane derivatives via Baeyer condensation of N,N-dimethylaniline with different active aromatic aldehyde compounds using amide ionic liquid as a catalyst. The syntheses were achieved for the first time using amide ionic liquid as a catalyst eliminating the need for a volatile organic solvent. The advantages of this ionic liquid are low cost and operational simplicity.

Halogen-free room-temperature bronsted acidic ionic liquid [Hmim]+ HSO4- as a recyclable green "dual reagent" catalysis for the synthesis of triarylmethanes (TRAM s) ;

The halogen-free Brnsted acidic ionic liquid methylimidazolium hydrogen sulfate ([Hmim]+ HSO4-) acts as a very efficient catalyst for the one-pot, two-component Baeyer condensation of a variety of aromatic aldehydes with dimethyl or diethyl aniline at room temperature. This green reagent behaves as both catalyst and solvent; that is, it exhibits dual-reagent catalysis. The room-temperature acidic ionic liquid could be recycled several times with almost no loss in the yield of the reaction. This is the first report of the Baeyer synthesis with a halogen-free ionic liquid.
