摘要
Several triazoles have been synthesized. They were obtained by a Cu-catalyzed cycloaddition of azides and alkynes. The reaction takes place in aqueous media under microwave irradiation using a copper catalyst based on porous glass. The products have been characterized by infrared, gas chromatography-mass spectrometry, H-1 NMR, and C-13 NMR in addition to melting=point determination. Furthermore the in situ building of some azides and alkynes and the influence of the used metal species was investigated.
