- Method for synthesizing amide compound by taking nitrile and diaryl methane as raw materials
-
The invention discloses a method for synthesizing an amide compound by taking nitrile and diaryl methane as raw materials, the method comprises the following steps: taking diaryl methane as a reaction raw material, nitrile as a raw material and a solvent, 2, 3-dichloro-5, 6-dinitrile group-1, 4-benzoquinone (DDQ) and tert-butyl nitrite (TBN) as catalysts, acid as an auxiliary agent and oxygen as an oxidizing agent, reacting under the conditions of normal temperature, normal pressure and blue light irradiation, and after the reaction is finished, carrying out separation treatment to obtain the amide compound. According to the method, the problem of metal residues in the product can be solved, oxygen is used as a terminal oxidizing agent, the method is environmentally friendly, and energy can be saved.

- Amberlyst-15 in ionic liquid: An efficient and recyclable reagent for nucleophilic substitution of alcohols and hydroamination of alkenes
-
The nucleophilic substitution reaction of secondary alcohols and hydroamination of alkenes with amides, sulfonamides, carbamates, and amines using Amberlyst-15 immobilized in [Bmim][BF4] (1-butyl-3- methylimidazolium tetrafluoroborate) ionic liquid as an efficient recyclable reagent is described. The solvent effect is prominent in the reaction, and the desired substitution products are obtained in good to excellent yield. The protocol is advantageous due to the ease of handling of the reagents, the simple work-up procedure, and the environmentally benign conditions that allow effective recyclability. A facile protocol involving Amberlyst-15 in the ionic liquid [Bmim][BF4] (= 1-butyl-3-methylimidazolium tetrafluoroborate) has been developed for nucleophilic substitution of alcohols and hydroamination of alkenes.

- Phosphotungstic acid catalyzed amidation of alcohols
-
Mild nucleophilic substitution reactions of benzhydrylic, benzylic, allylic, and simple aliphatic alcohols with sulfonamides, benzamide, and 4-nitroaniline in the presence of 12-phosphotungstic acid as an efficient, eco-friendly, cheap, and air- and moisture-tolerant catalyst for the construction of C-N bonds has been investigated. The amine derivatives were obtained in good yields (up to 98%). The reusable nature of the 12-phosphotungstic acid makes this protocol more attractive. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.
