Sharma, Rohit published the artcileMetal-Free Ionic-Liquid-Mediated Synthesis of Benzimidazoles and Quinazolin-4(3H)-ones from Benzylamines, Product Details of C19H14N2, the publication is Asian Journal of Organic Chemistry (2017), 6(10), 1370-1374, database is CAplus.
An expedient metal-free synthetic protocol for the construction of benzimidazoles I (R = C6H5, 4-FC6H4, 3-ClC6H4, etc.; X = H, C6H5) has been developed from o-phenylenediamine and benzylamine, using an imidazolium-based ionic liquid as the reaction medium. The reactions proceed by oxidation of benzylamine derivatives to their corresponding imines, followed by intramol. cyclization, to yield benzimidazoles. Advantages of this method include: an environmentally friendly metal-free process, recyclable reaction media, high yields, short reaction times, and the applicability for the synthesis of quinazolin-4(3H)-ones III (R = C6H4, 4-ClC6H4, 3-BrC6H4, etc.). An NMR spectroscopy study provided further insight into the reaction.
