Functional ion liquid method for catalytic synthesis of amine compounds

The invention discloses a method for synthesizing an amine compound catalyzed by functionalized ionic liquid. According to the method, functionalized ionic liquid is used as a catalyst to catalyze N-alkylation of amine and alcohol to synthesize corresponding compound derivatives. Acid functionalized ionic liquid is used as the catalyst to synthesize a series of compounds of amine. The method has the following advantages: a catalytic system is a metal-free system; the usage amount of the catalyst is small, and the catalyst has high catalytic activity, good stability and low corrosivity; operation is simple, and reaction is mild; post-treatment is easy, and the catalyst can be cyclically used.

Sulfonic acid-functionalized ionic liquids as metal-free, efficient and reusable catalysts for direct amination of alcohols

A series of sulfonic acid-functionalized (SO3H-functionalized) ionic liquids was synthesized and used as metal-free, highly selective and efficient catalysts for the direct amination of alcohols. Notably, the activities of the series of SO3H-functionalized ionic liquids were compared and a 92% isolated yield was obtained using 3-tetradecyl-1-(butyl-4- sulfonyl)imidazolium trifluoromethanesulfonate ([BsTdIM][OTf]) as the catalyst. Importantly, the catalytic system has wide substrate scope including benzylic, allyl, propargylic, aliphatic alcohols with sulfonamide, amide, carbamate, aromatic amine and N-heterocyclic compounds. Interestingly, the system was also suitable for a multi-gram scale direct amination of alcohols. Additionally, the reusable nature of [BsTdIM][OTf] makes this protocol more attractive and avoids the disposal and neutralization of acidic catalysts. Moreover, preliminary experiments indicated that this reaction should proceed via an SN1 pathway. Copyright

Rhodium-catalyzed arylation of α-amido sulfones with arylboronic acids in a water-toluene biphasic system

An efficient method for the synthesis of N-protected diaryl-methyl-amines was developed through a rhodium-catalyzed arylation of α-amido sulfones with arylboronic acids in a water-toluene biphasic system. The use of a base combined with a surfactant playe
