Ruthenium-catalyzed azide alkyne cycloaddition reaction: scope, mechanism and applications [PDF]

, 2016
The ruthenium-catalyzed azide alkyne cycloaddition (RuAAC) affords 1,5-disubstituted 1,2,3-triazoles in one step and complements the more established copper-catalyzed reaction providing the 1,4-isomer.

Linker‐Free Covalent DNA Functionalization of Quantum‐Grade Nanodiamonds

Advanced Optical Materials, EarlyView.
Nanodiamond (ND) surface is terminated with azide groups via nucleophilic substitution and decarboxylative azidation. The resulting azidated NDs display high click reactivity while retaining the spin and charge properties of nitrogen‐vacancy centers.

Ruthenium‐Catalyzed Azide‐Selenoalkyne Cycloadditions: A Combined Synthetic–Computational Study into Reaction Scope, Mechanism, and Origins of Regioselectivity

Advanced Synthesis &Catalysis, EarlyView.
A ruthenium‐catalyzed azide–alkyne cycloaddition (RuAAC) reaction is reported for the synthesis of selenium‐substituted triazole products. Reaction regioselectivity is dependent on the identity of the non‐selenium substituent of the alkyne, which challenges the perceived understanding of RuAAC regioselectivity.

Transformations of 1-(Oxiranylmethyl)-1,2,3-triazoles into 2-(Oxiranyl­methyl)-1,2,3-triazoles and Alkanenitriles [PDF]

Synlett, 2012
New reactions for the transformation of 1-(oxiranylmethyl)-1,2,3-triazoles into 2-(oxiranylmethyl)-1,2,3-triazoles or alkanenitriles were established. Successive treatment of the substrate with triflic acid and t-BuOH afforded 4,6-dihydro-5-hydroxy-1,3a,6a-triazapentalene derivative.

N‐Containing Carbon Materials in Metal‐Free and Non‐Noble Metal Liquid Phase Heterogenous Catalysis

Advanced Synthesis &Catalysis, EarlyView.
Over 100 examples of non‐noble metal supported on N‐containing and metal‐free N‐containing carbon catalysts are discussed. Particular emphasis is put on how different N‐functionalities influence catalyst performance and stability. Preparation procedures are also examined, with a strong focus on how the heat treatment temperature influences N ...

Synthesis and Cytotoxic Evaluation of 1H-1,2,3-Triazol-1-ylmethyl-2,3-dihydronaphtho[1,2-b]furan-4,5-diones

Anais da Academia Brasileira de Ciências, 2018
The 1,2-naphthoquinone compound was previously considered active against solid tumors. Moreover, glycosidase inhibitors such as 1,2,3-1H triazoles has been pointed out as efficient compounds in anticancer activity studies.
