4-Sulfanyl-1,2,3-triazole as a Powerful Ligand in CuAAC to Synthesize 1,4-Substituted 1,2,3-Triazoles Under Solvent-Free and Low Catalyst Loading [PDF]

Molecules
4-Sulfanyl-1,2,3-triazole (L1) accelerated the solvent-free CuAAC efficiently with low catalyst loading (0.1 mol% for common azides and 1 mol% for sulfonyl azides). L1 exhibited higher catalytic activity compared to 1,4-substituted 1,2,3-triazole without

Ortho-Phosphinoarenesulfonamide-Mediated Staudinger Reduction of Aryl and Alkyl Azides

Molecules, 2022
Conventional Staudinger reductions of organic azides are sluggish with aryl or bulky aliphatic azides. In addition, Staudinger reduction usually requires a large excess of water to promote the decomposition of the aza-ylide intermediate into phosphine ...

Kinetic resolution of cyclic benzylic azides enabled by site- and enantioselective C(sp3)–H oxidation

Nature Communications, 2022
Catalytic kinetic resolution of racemates is among the best ways to prepare enantiopure compounds, but this process is difficult with organic azides given the small size of the azido group.
