monophosphine 1 (ClickPhos) has been prepared via efficient 1,3-dipolar cycloadditions of readily available azides and acetylenes. Palladium complexes derived from these ligands provide highlyactivecatalysts for Suzuki-Miyaura coupling and amination reactions of arylchlorides.
Synthesis of functionalized 1,2,3-triazoles using Bi<sub>2</sub>WO<sub>6</sub> nanoparticles as efficient and reusable heterogeneous catalyst in aqueous medium
The regioselective synthesis of functionalized triazoles is achieved using a combination of Bi2WO6 nanoparticles (10 mol%) and click conditions from β-nitrostyrenes, phenylacetylene and chalcones with azides.

ABSTRACT This article describes the synthesis of a new phosphine free tetradentate Pd catalyst using dl-2,3-diaminopropionic acid. The complex was characterized by Mass, IR, and 1H NMR. The catalyst is air stable at room temperature and non-hygroscopic. Application of this new catalyst to regioselective C–H activation on 1-substituted 1,2,3-triazole and indoles with aryl iodides to get corresponding
