Dicationic Ionic Liquid as the Recyclable Catalyst for the Synthesis of Quinoxaline Derivatives
An efficient and eco-friendly protocol for the synthesis of quinoxaline derivatives employing a condensation reaction between 1,2-diketone and 1,2-diaminobenzene derivative has been developed. The reaction of 1,2-diketone and 1,2-diaminobenzene derivative was carried out in water at room temperature using 10 mol% of task-specific dicationic ionic liquid as a catalyst. The results show that...
متن کاملIonic Liquid an Efficient Solvent and Catalyst for Synthesis of 1-aminoalkyl-2-naphthol and Naphthoxazine Derivatives
The aim of doing this research is a one-pot three-component synthesis of 1-aminoalkyl-2- naphthol and naphthoxazine derivatives using the condensation of β-naphthol with various aldehydes and amines in the presence of ionic liquid {[(secondary butyl) methyl] imidazolium bromide} {[sec-bmim]+ Br-, as an efficient catalyst and solvent. The catalyst was prepared according...

Vitamin C as a green and efficient catalyst in synthesis of quinoxaline derivatives at room temperature
A simple, highly efficient and green procedure for the condensation of o-phenylenediamines with 1, 2-dicarbonyl compounds in the presence of vitamin C, as an inexpensive organocatalyst, is described. Using this method, variety of quinoxaline derivatives with different electron releasing and electron withdrawing substituents, are produced in high to excellent yields at room temperature in ethano...
