Crystal Structure and Solid-State Properties of Discrete Hexa Cationic Trinuclear Zinc Triazole Cluster [PDF]
, 2015 A linear trinuclear cluster of the type [{Zn3(HTrz)6(H2O)6}6+(NO3 -)6(H2O)] (ZnT) has been synthesized by one-pot reaction between 1,2,4-triazole and Zn(NO3).6H2O.

Biotechnology and Applied Biochemistry, EarlyView.ABSTRACT Macrocyclic calix[n]arenes have many applications, with diverse structures that can easily be functionalized either on upper or lower rims, mostly to impart solubility and improve biological activities. In this study, triazole‐based p‐tert‐butylcalix[4]arene conjugates (AT10a and AT10b) and their p‐tert‐butylphenol analogs (AT10b and AT11b ...

1H-1,2,4-Triazole-3-carboxamide [PDF]
Acta Crystallographica Section E Structure Reports Online, 2008 Planar mol-ecules of the title compound, C(3)H(4)N(4)O, are organized into sheets by extensive N-H⋯O and N-H⋯N hydrogen bonding in the (101) plane of the crystal structure. These hydrogen bonds may also stabilize the mol-ecule in the Z form. The title compound is in the amide form, as shown by the C=O bond length [1.252 (2) Å].

Catalysis in Chemical Modification of Proteins
ChemCatChem, EarlyView.Catalytic principles of synthetic organic chemistry have been increasingly applied to chemical modification of proteins during the recent years. This review article describes how seven types of catalytic systems —electrocatalysis, photocatalysis, metal catalysis, acid catalysis, organocatalysis, supramolecular catalysis, and heterogeneous catalysis ...

[CuI(PPh3)3]‐Mediated Arylation of 1,2,3‐Triazoles
ChemCatChem, EarlyView.Arylation reactions are a powerful strategy to selectively prepare highly substituted heterocyles. Herein, the arylation of 1,4‐disubstituted 1,2,3‐triazoles with [CuI(PPh3)3] is reported in the presence of air and moisture. Suitable substrates include triazoles containing a pyridyl group, which are of interest in applications such as ancillary ligands

ChemCatChem, Accepted Article.We investigate the effect of iron(II) spin state on the catalytic activity of a spin‐crossover complex, specifically [Fe(NH2trz)3](NO3)2, in an acetalization reaction. Thanks to its bistability, this complex enables the evaluation of its catalytic activity in both the high‐spin and low‐spin states under identical experimental conditions, thereby ...
