DOI: 10.1016/j.jorganchem.2017.09.024

Abstract: Abstract A series of Cu-N-heterocyclic carbene (Cu-NHC) complexes, 3a-c , were synthesized and characterized by spectroscopic methods such as NMR, HRMS and elemental analysis. The performance of these (Cu-NHC) complexes, 3a-c showed excellent activity in… read more here.

DOI: 10.1021/jacs.2c01985

Abstract: Significant advances have been achieved for the construction of chiral skeletons containing 1,2,3-triazoles via transition-metal-catalyzed asymmetric azide-alkyne cycloaddition; however, most of them have been limited to terminal alkynes in the synthesis of central chirality via… read more here.

DOI: 10.1039/c8py01004h

Abstract: The kinetics of photoinduced copper(I) catalyzed azide-alkyne cycloaddition (CuAAC) polymerizations were assessed as a function of copper(II) amine-based ligands. Copper(II) bromide ligated with 1,1,4,7,10,10-hexamethylenetetramine (HMTETA) exhibited the fastest kinetics in both Norrish type(I) and type(II)… read more here.

DOI: 10.1039/d0cc06348g

Abstract: A novel ligand (6) for copper-catalyzed azide-alkyne cycloaddition (CuAAC) in bioconjugation has been developed. Both in vitro and in vivo experiments indicate that 6 is more efficient and less cytotoxic than the canonical CuAAC ligands.… read more here.

DOI: 10.3390/polym15092199

Abstract: Ruthenium(II)-catalyzed azide–alkyne cycloaddition (RuAAC) polymerization of t-butyl 4-azido-5-hexynoate (tBuAH), i.e., a heterobifunctional monomer carrying azide and alkyne moieties, was investigated in this study. RuAAC of the monofunctional precursors of tBuAH yielded a dimer possessing a… read more here.
