A convenient synthesis of 4-alkynyl-1,2,3-triazoles and novel unsym. substituted 4,4′-bi-1,2,3-triazole derivatives has been devised starting from easily available 1-trimethylsilyl-1,3-butadiyne. The starting compound was reacted with several azides, leading to 4-(silylalkynyl)-1,2,3-triazoles, which were easily transformed into 4-arylalkynyl-1,2,3-triazoles by a Pd catalyzed coupling reaction with aryl iodides, or into novel 4,4′-bis-1,2,3-triazole derivatives by a subsequent cyclization reaction with azides.
