Potassium tert -Butoxide Promoted Synthesis of 4,5-Diaryl-2 H -1,2,3-triazoles from Tosylhydrazones and Nitriles

Intermolecular cycloaddition of tosylhydrazones with nitriles was investigated. t -BuOK was shown to be an excellent base for increasing the effectiveness of the reaction in this protocol, and homocoupling of the tosylhydrazones was significantly inhibited by using xylene as a solvent. Through this transformation, a variety of 4,5-diaryl-2 H -1,2,3-triazoles were prepared in good to excellent yields and with high purities. The process is azide-free and transition-metal-free.
