Ruthenium-Catalyzed Azide Alkyne Cycloaddition Reaction: Scope, Mechanism, and Applications
Chemical Reviews, 2016 The ruthenium-catalyzed azide alkyne cycloaddition (RuAAC) affords 1,5-disubstituted 1,2,3-triazoles in one step and complements the more established copper-catalyzed reaction providing the 1,4-isomer.

Stereoselective synthesis of (E)-vinyl alkyl sulfides via hydrozirconation of terminal alkynes [PDF]
Journal of the Serbian Chemical Society, 2004 Terminal alkynes react with Cp2Zr(H)Cl (Cp = μ5-C5H5) to give organozirconium complexes, which are trapped with alkylsulfenyl chlorides to afford (E)-vinyl alkyl sulfides in good yield.

Control of zeolite pore interior for chemoselective alkyne/olefin separations
Science, 2020 Zeolites that prefer alkynes Alkenes such as ethylene and propene must be separated from alkynes before they can be converted in polymers. Drawbacks in current methods, such as hydrogenation of alkynes producing unwanted alkanes, has spurred interest in ...
