Pyridine-phosphinimine ligand-accelerated Cu(<scp>i</scp>)-catalyzed azide–alkyne cycloaddition for preparation of 1-(pyridin-2-yl)-1,2,3-triazole derivatives
5-a]pyridines and alkynes for the first time. By optimizing the reaction conditions, an efficient catalytic system (CuCl/2-PyCH2N[double bond, length as m-dash]P(t)Bu3) was developed to give 1-(pyridin-2-yl)-1,2,3-triazole derivatives in moderate to excellent yields (46-98%).

metal–carbonyl complexes SCoMPIs for single-core multimodal probes for imaging. Re(I) tricarbonylcomplexes have unique photophysical properties allowing for their unequivocal detection in cells but also present some weaknesses such as a very low luminescence quantum yield in aqueous medium. Further optimizations would thus be desirable. We therefore developed new Re(I) tricarbonylcomplexes prepared from
