Ruthenium-catalyzed cycloaddition of alkynes and organic azides
TL;DR: In this article, a convenient process for the regioselective synthesis of 1,5-disubstituted 1,2,3-triazoles and 1,4,5-trisubstitized 1, 2,3, 4,5, 5 triazoles from organic azides and alkynes employs catalytic ruthenium.
Journal ArticleDOI

TL;DR: The ruthenium-catalyzed azide-alkyne cycloaddition (RuAAC) appears to proceed via oxidative coupling of the azide and alkyne reactants to give a six-membered rUThenacycle intermediate, in which the first new carbon-nitrogen bond is formed between the more electronegative carbon of the alkynes and the terminal, electrophilic nitrogen of the Azide.

TL;DR: Cp*RuCl(PPh3)2 is an effective catalyst for the regioselective "fusion" of organic azides and terminal alkynes, producing 1,5-disubstituted 1,2,3-triazoles.
Journal ArticleDOI
Iridium-Catalyzed Intermolecular Azide–Alkyne Cycloaddition of Internal Thioalkynes under Mild Conditions†
TL;DR: An iridium-catalyzed azide-alkyne cycloaddition reaction (IrAAC) of electron-rich internal alkynes is described, which is the first efficient intermolecular AAC of internal thioalkynes.
Journal ArticleDOI
Recent progress in the chemistry of osmium carbyne and metallabenzyne complexes
TL;DR: There has been much research activity in the chemistry of osmium-carbyne and osmabenzynes complexes as discussed by the authors, and recent progress in the synthesis, reactivities, and structural properties of these complexes have been summarized in the literature.
