Abstract
Synthesis of the first representative of a 5-formyl-1H-1,2,3-triazole-4-carboxylic acids series – 1-(4-ethoxyphenyl)-5-formyl-1H-1,2,3-triazole-4-carboxylic acid was performed. The 1-azido-4-ethoxybenzene was chosen as a starting reagent in a two-step synthesis, which reacted with the ethyl 4,4-diethoxy-3-oxobutanoate under base catalysis to form ethyl 5-(diethoxymethyl)-1-(4-ethoxyphenyl)-1H-1,2,3-triazole-4-carboxylate with protected formyl and acid groups. By the subsequent saponification of the ester group and removing of acetal protection, the target 1-(4-ethoxyphenyl)-5-formyl-1H-1,2,3-triazole-4-carboxylic acid was obtained. It has been found that the free acid form predominated in the solution under its cyclic 6-hydroxy-1,6-dihydro-4H-furo[3,4-d][1,2,3]triazol-4-one tautomer. According to 1H NMR, cyclic hemiacetal is about 20%.

Abstract
For the first time, 5-formyl-1-(pyridin-3-yl)-1H-1,2,3-triazole-4-carboxylate was synthesized via a two-step scheme. The molecular structure of the compound was determined by a single-crystal X-ray diffraction analysis. The Hirshfeld surface analysis was used to study various intermolecular interactions. The crystalline structure is marked by the presence of three types of π-interactions (n→π*, lp···π, and π···π) between the -C(H)=O group and triazole rings. The compound is a versatile polyfunctional building block for construction of annulated 1,2,3-triazoles.

Abstract
The title compound, C17H7F8N3O, was obtained via the reaction of 1-azido-2,3,4,5,6-penta-fluoro-benzene with 4,4,4-tri-fluoro-1-(p-tol-yl)butane-1,3-dione using tri-ethyl-amine as a base catalyst and solvent. The dihedral angles between the penta-fluoro-phenyl (A), triazole (B) and p-tolyl (C) rings are A/B = 62.3 (2), B/C = 43.9 (3) and A/C = 19.1 (3)°. In the crystal, the mol-ecules are linked by C-H⋯F and C-H⋯O hydrogen bonds as well as by aromatic π-π stacking inter-actions into a three-dimensional network. To further analyse the inter-molecular inter-actions, a Hirshfeld surface analysis was performed.

Abstract
An overview of the latest developments in the metal-free synthesis of non-benzo-fused N-functionalized and NH-1,2,3-triazoles is provided in this feature article. Synthetic studies that appeared from 2016 until August 2020 are organized according to a wide-ranging classification, comprising oxidative and eliminative azide-dipolarophile cycloadditions, diazo transfer reactions and N-tosylhydrazone-mediated syntheses. The newly developed methods constitute a significant contribution to the field of 1,2,3-triazole synthesis in terms of structural variation via either the exploration of novel reactions, or the exploitation of existing methodologies.

Abstract
The title compound, C19H17ClN4O2, was obtained via a two-step synthesis involving the enol-mediated click Dimroth reaction of 4-azido-anisole with methyl 3-cyclo-propyl-3-oxo-propano-ate leading to the 5-cyclo-propyl-1-(4-meth-oxy-phen-yl)-1H-1,2,3-triazole-4-carb-oxy-lic acid and subsequent acid amidation with 4-chloro-aniline by 1,1'-carbonyl-diimidazole (CDI). It crystallizes in space group P21/n, with one mol-ecule in the asymmetric unit. In the extended structure, two mol-ecules arranged in a near coplanar fashion relative to the triazole ring planes are inter-connected by N-H⋯N and C-H⋯N hydrogen bonds into a homodimer. The formation of dimers is a consequence of the above inter-action and the edge-to-face stacking of aromatic rings, which are turned by 58.0 (3)° relative to each other. The dimers are linked by C-H⋯O inter-actions into ribbons. DFT calculations demonstrate that the frontier mol-ecular orbitals are well separated in energy and the HOMO is largely localized on the 4-chloro-phenyl amide motif while the LUMO is associated with aryl-triazole grouping. A Hirshfeld surface analysis was performed to further analyse the inter-molecular inter-actions.
