Molecules, 2015 We present a trifunctional scaffold designed for the solid-phase synthesis of trimodal compounds. This scaffold holds two alkyne arms in a free and TIPS-protected form for consecutive CuAAC (copper(I)-catalyzed azide–alkyne cycloaddition), one Fmoc ...

Triazole-Directed Pd-Catalyzed C(sp2)–H Oxygenation of Arenes and Alkenes [PDF]
, 2016 Selective Pd-catalyzed C(sp2)–H oxygenation of 4-substituted 1,2,3-triazoles is described. Unlike previous metal-catalyzed C–H functionalization events, which preferentially occur at the activated heterocyclic C–H bond, the regioselective oxygenation of ...

Polypropylene-based graft copolymers via CuAAC click chemistry
eXPRESS Polymer Letters, 2018 Graft copolymers from commercial chlorinated polypropylene (PP-Cl) possessing either poly(ethylene glycol) (PEG) or poly(ε-caprolactone) (PCL) grafts are synthesized by copper (I)-catalyzed azide-alkyne cycloaddition ‘click’ reaction (CuAAC).

Coordinatively unsaturated ruthenium complexes as efficient alkyne-azide cycloaddition catalysts [PDF]
, 2012 The performance of 16-electron ruthenium complexes with the general formula Cp*Ru(L)X (in which L = phosphine or N-heterocyclic carbene ligand; X = Cl or OCH2CF3) was explored in azide−alkyne cycloaddition reactions that afford the 1,2,3- triazole ...

Synthesis of Fluorescent Poly(coumarin-triazoles) via a CuAAC 'click' reaction [PDF]
South African Journal of Chemistry, 2017 We describe a new fluorescent polymer system based on a coumarin-triazole functionality. The non-fluorescent 3-azido-coumarin-alkyne monomers are polymerized in a step-growth manner via a Cu (I)-catalyzed 1,3-dipolar cycloaddition (CuAAC) reaction. The process involves the conversion of a quenching azide group to 1,2,3-triazole in the monomer that ...

Postsynthetic modification of zirconium metal-organic frameworks [PDF]
, 2016 Metal-organic frameworks (MOFs) have been in the spotlight for a number of years due to their chemical and topological versatility. As MOF research has progressed, highly functionalised materials have become desirable for specific applications, and in ...

Solvent-Free Copper-Catalyzed Azide-Alkyne Cycloaddition under Mechanochemical Activation
Molecules, 2015 The ball-mill-based mechanochemical activation of metallic copper powder facilitates solvent-free alkyne-azide click reactions (CuAAC). All parameters that affect reaction rate (i.e., milling time, revolutions/min, size and milling ball number) have been
