Title
First application of bismuth triflate as an efficient, non-transition metallic and reusable catalyst for aromatic nitration
Abstract

Bismuth(III) triflate [Bi(OTf)3] has been found to be efficient and reusable in catalyzing the aromatic nitration using HNO3 as the direct nitrating reagent with toluene as the model substrate. In the presence of 4 mol% Bi(OTf)3, toluene could be converted entirely to nitrotoluenes with a bit excess of HNO3 within 6 h in refluxing 1,2-dichloroethane. And Bi(OTf)3 can be easily recycled five times without loss of activity. The nitration protocol is both economical and environmentally friendly.
