A new approach for the synthesis of highly pharmaceutically relevant 4-fluoropyrazoles via oxidative annulation of α-fluoronitroalkenes with in situ prepared hydrazones was developed. The reaction is efficiently promoted by trifluoroacetic acid while atmo

This work described a one-pot tandem three-component synthesis of 2,4,5-triaryl-2,4-dihydro-3H-1,2,4-triazol-3-ones using a simple reaction between phenylhydrazines, benzaldehydes and phenyl isocyanates under microwave irradiation and solvent-free conditi
