1‑Iodobuta-1,3-diynes in Copper-Catalyzed Azide–Alkyne Cycloaddition: A One-Step Route to 4‑Ethynyl-5-iodo-1,2,3-triazoles [PDF]
Cu-catalyzed 1,3-dipolar cycloaddition of iododiacetylenes with organic azides using iodotris(triphenylphosphine)copper(I) as a catalyst was found to be an efficient one-step synthetic route to 5-iodo-4-ethynyltriazoles. The reaction is tolerant to

Synthesis and antibacterial evaluation of sulfonamide bridged disubstituted 1,2,3-triazoles [PDF]
In the present study, a series of sulfonamide bridged 1,4-disubstituted 1,2,3-triazoles have been synthesized in good yield via click reaction between sulfonamide linked terminal alkynes and in situ prepared 2/3/4-azidobenzenesulfonamides.

Catalytic Asymmetric Synthesis of Atropisomeric N‑Aryl 1,2,4-Triazoles [PDF]
The atroposelective synthesis of N-aryl 1,2,4-triazoles was developed. A cyclodehydration reaction was rendered asymmetric with the use of a chiral phosphoric acid catalyst to afford atropisomeric N-aryl 1,2,4-triazoles in up to 91:9 er ...

Synthesis of 1‑Cyanoalkynes and Their Ruthenium(II)-Catalyzed Cycloaddition with Organic Azides to Afford 4‑Cyano-1,2,3-triazoles [PDF]
A new method to convert terminal alkynes under relatively mild conditions to 1-cyanoalkynes using in situ formed cyanogen is described. 1-Cyanoalkynes have a higher reactivity than terminal alkynes in the ruthenium(II)-catalyzed regiospecific azide ...
