, p. 502 - 506 (2014)
A novel method is described to prepare rutile TiO2 nanoparticles which are reusable and efficient heterogeneous catalysts for the synthesis of thiotetrazoles and arylaminotetrazoles - compounds widely used in medicinal and coordination chemistry. This procedure has the advantages of good to excellent yields of products, elimination of homogeneous catalysts and toxic and explosive reagents, simple methodology, easy work up and the reusability of the heterogeneous catalyst.

A simple and efficient route for the synthesis of a series of 5-substituted 1 H -tetrazoles using l -proline as a catalyst from structurally diverse organic nitriles and sodium azide is reported. The prominent features of this environmentally benign, cost effective, and high-yielding l -proline-catalyzed protocol includes simple experimental procedure, short reaction time, simple workup, and excellent yields making it a safer and economical alternative to hazardous Lewis acid catalyzed methods. The protocol was successfully applied to a broad range of substrates, including aliphatic and aryl nitriles, organic thiocyanates, and cyanamides.
