NbCl5 as an Efficient Catalyst for Rapid Synthesis of Quinoxaline Derivatives

[摘要]：A series of quinoxaline derivatives have been synthesized in excellent yields by the condensation of 1,2-diketones and 1,2-phenylenediamines in the presence of a catalytic amount of NbCl5 at room temperature in short times.
