Synthesis of triazoles by electro-assisted click reaction using a copper foil electrode

This paper presents an innovative pathway for the synthesis of triazoles using the well-known "click chemistry"assisted by the electrochemical oxidation of metallic Cu0. The click reaction is used to couple a wide range of biological interest compounds. I

A comparative study between Cu(INA)2-MOF and [Cu(INA)2(H2O)4] complex for a click reaction and the Biginelli reaction under solvent-free conditions

The catalytic activity of metal-organic framework Cu(INA)2 (INA = isonicotinate ion) and the complex [Cu(INA)2(H2O)4] were studied in the Copper-catalyzed Azide-Alkyne Cycloaddition (CuAAC) and Biginelli reactio

Synthesis of heterogeneous Ru(ii)-1,2,3-triazole catalyst supported over SBA-15: Application to the hydrogen transfer reaction and unusual highly selective 1,4-disubstituted triazole formation: Via multicomponent click reaction

In the present study, we demonstrate a simple and efficient method for ligand formation and covalent anchoring to a heterogeneous support via click reaction. The complex tris(triphenylphosphine)ruthenium(ii) dichloride [RuCl2(PPh3)3] anchored over the click modified ligand of SBA-15 forms a new highly efficient heterogeneous SBA-15-Tz-Ru(ii)TPP catalyst. Solid state 13C, 29Si, and 31P CP-MAS NMR spectra provide evidence for the formation of the heterogeneous catalyst. SBA-15-Tz-Ru(ii)TPP catalyst was screened for the multicomponent click cycloaddition reaction in water medium as a green solvent and it exhibited unusual and excellent selectivity for the formation of 1,4-disubstituted triazole product under mild reaction condition. In addition, SBA-15-Tz-Ru(ii)TPP catalyst also catalyzed the hydrogen transfer reaction of various carbonyl compounds with excellent catalytic activity to give the corresponding alcohols. The heterogeneous catalyst can be recycled and reused several times (five) without a loss in reactivity.

ZrCl4-mediated synthesis of 1,2,3-triazoles from vinyl nitrates and their biological evaluation

A ZrCl4-mediated simple method for the conversion of vinyl nitrates to 1,2,3-triazoles in excellent yields is developed. The obtained new triazoles were evaluated for their antimicrobial activity.

New cyclometalated iridium(III) dye chromophore complexes for n-type dye-sensitised solar cells

The synthesis of seven iridium complexes where aryl-1,2,3-triazole (Ar-tz) moieties act as cyclometalating ligands with 2,2′-bipyridyl-4,4′-dicarboxylic acid (dcb) as a N^N ancillary/anchoring ligand, is described. The new dye complexes [Ir(Ar-tz)2(dcb)][PF6] (AS1-7) were prepared in a two stage procedure with iridium-chloride dimer isolation. DFT analysis together with photophysical investigations reveal how using different substituents on the phenyl ring, or a different aryl system, lead to the tuning of the absorption and emission properties of these complexes. Computational studies therefore demonstrate an ideal HOMO-LUMO directionality for the [Ir(Ar-tz)2(dcb)]+framework, promoting a favourable electron transfer into the TiO2conduction band upon photoexcitation. Preliminary unoptimized tests on TiO2DSSCs have been carried out which show similar photovoltaic performance to the [Ir(ppy)2(dcb)][PF6] (ppy = 2-phenylpyridine) benchmark.

Selective formation of 1,4-disubstituted triazoles from ruthenium-catalyzed cycloaddition of terminal alkynes and organic azides: Scope and reaction mechanism

The catalytic activity of a series of ruthenium complexes lacking cyclopentadienyl ligands has been evaluated for the cycloaddition of terminal alkynes and azides to give selectively 1,4-disubstituted 1,2,3-triazoles. The complex RuH(η2-BH

One-pot click synthesis of 1N-alkyl-4-aryl-1,2,3-triazoles from protected arylalkynes and alkyl bromides

1N-Alkyl-4-aryl-1,2,3-triazoles have been prepared through a multicomponent one-pot protocol from the corresponding (arylethynyl)trimethylsilanes and alkyl bromides. In situ alkyl azide formation and alkyne deprotection followed by copper(I)-catalyzed click cycloaddition afforded the desired 1,4-disubstituted 1,2,3-triazoles in generally good to excellent yield, with only minor observation of the undesired 1,5-regioisomeric cycloadduct. The protocol eliminates the need to use reactive organic azides and terminal alkynes. Georg Thieme Verlag Stuttgart. New York.

In this paper the synthesis of a library of new 1,4-disubstituted 1,2,3-triazoles 1, with a variety of additional functional groups on its structure, from an in situ generated benzyl azide 2 and different alkynes and dialkynes 3 is reported. Optimal exper

Aryl halides can be easily transformed in a one-pot procedure into 4-aryl-1,2,3-triazoles with palladium/copper-catalyzed Sonogashira-click reaction sequence, using trimethylsilylacetylene as acetylene surrogate.
