A concise one-pot three-component reaction of organic halides­, terminal acetylenes, and sodium azide provided an efficient route for the synthesis of 1,2,3-triazoles. A variety of 1,2,3-triazoles were prepared in good to excellent yields with green solvent glycerol. This procedure used CuI and diethylamine, which are two easily available reagents as the new catalytic system at room temperature.

A novel catalytic system consisting of I2-SDS-H2O has been developed which cleaves 2,3-diaza-1,3-butadiene, 1-aza-1,3-butadienes, oximes and in presence of indoles in the medium uses the corresponding aldehyde products to produce bis(indolyl)alkanes in situ. This one pot simple and mild dual catalytic system works in water at room temperature under neutral conditions.

A simple economical, and highly efficient catalytic system for the synthesis of diaryl sulfides by a copper-catalysed coupling of aryl halides and thioacetate in water has been developed. A variety of aryl halides reacted with thioacetate to give the desired products in high yields up to 95%. The present catalysis protocol tolerated a wide range of functional groups, including amino, fluoro, and carboxyl moieties.
