In the title compound, [K(2)(C(8)H(6)N(3)O(2))(2)(H(2)O)](n), each K(+) ion is seven-coordinated by one O atom from a bridging water mol-ecule, five carboxyl-ate O atoms and one N atom from a benzotriazole group, forming a distorted mono-capped octa-hedral geometry. In the crystal, the carboxyl-ate groups act as bridging ligands, forming a two-dimensional polymer parallel to (001). The aqua lig...

In the title compound, C(14)H(13)N(3)O, the benzotriazole ring is oriented at a dihedral angle of 13.43 (4)° with respect to the phenyl ring. In the crystal structure, inter-molecular O-H⋯N hydrogen bonds link the mol-ecules into chains along the b axis. Aromatic π-π contacts between benzene rings and between triazole and benzene rings [centroid-centroid distances = 3.8133 (8) and 3.7810 (8) Å,...

The anticorrosive agents 1H-benzotriazole (1H-BT), 4-methyl-1H-benzotriazole (4 Me-BT) and 5-methyl-1H-benzotriazole (5 Me-BT), which are usually added to dishwasher detergents, automotive antifreeze formulations and aircraft de-icing/anti-icing fluids (ADAFs), were measured in river water. Samples were collected from 15 sampling sites in the mainstream and selected tributaries of a medium-size...

In the title compound, [HgCl(2)(C(15)H(13)N(5))(2)], the Hg(II) atom is located on a twofold rotation axis and resides in a distorted tetra-hedral coordination environment composed of two Cl atoms and two N atoms from two 1-(2-methyl-benzimidazol-1-ylmeth-yl)benzotriazole ligands.

In this work, the degradation performance for photocatalytic oxidation of eight micro-pollutants (amisulpride, benzotriazole, candesartan, carbamazepine, diclofenac, gabapentin, methlybenzotriazole, and metoprolol) within real secondary effluent was investigated using three different reactor designs. For all types, influence irradiation power on its reaction rate energetic efficiency investigat...

The mol-ecular geometry of the title compound, C(7)H(7)N(3)O(2)S, does not differ much from that of the previously reported 4-toluene-sulfonyl analogue. Unlike the latter compound, however, mol-ecules of the title compound associate primarily via π-π stacking inter-actions of their benzene rings [centroid-centroid distance = 3.5865 (8) Å], forming columnar stacks along the crystallographic 2(1)...

An efficient procedure has been developed for the preparation of tetrasubstituted unsymmetrical 1,4-enediones via copper-promoted autotandem catalysis and air as the oxidant. Various N-nucleophiles are compatible with this reaction, such as morpholine, piperidine, pyrrolidine, arylamines, pyrazole, imidazole, benzimidazole, and benzotriazole. This reaction also has significant advantages in eas...

A modular synthetic method for bis- and tris-1,2,3-triazoles that include a benzotriazole structure was developed on the basis of sequential azide-aryne and azide-alkyne cycloadditions. The key to success was efficient halogen-metal exchange reaction-mediated generation of aryne from ortho-iodoaryl triflates bearing a base-sensitive terminal alkyne moiety, which was achieved using trimethylsily...

Benzotriazole-mediated syntheses led to novel bis-conjugates of quinine with quinolone antibiotics and amino acid linkers which were successfully prepared by two alternative routes with excellent yields and retention of chirality. These bis conjugates retain in vitro antimalarial activity with IC(50) values ranging from 12 to 207 nM, similar to quinine itself.
