4-(4H-1,2,4-Triazol-4-yl)benzoic acid (cas: 157069-48-2) belongs to triazole derivatives. The many free lone pairs in triazoles make them useful as coordination compounds, although not typically as haptic ligands. 1,2,3-Triazoles are usually prepared following (3+2) cycloaddition protocols. A common technique for unsubstituted triazoles is the Huisgen azide-alkyne 1,3-dipolar cycloaddition: a azide and an alkyne react at high temperature to form a ring. However, the Huisgen strategy produces a mixture of isomers (typically 1,4- and 1,5-disubstituted) when used to produce substituted triazoles.Application In Synthesis of 4-(4H-1,2,4-Triazol-4-yl)benzoic acid

Three organic ligands bearing 1,2,4-triazolyl donor moieties, (S)-4-(1-phenylpropyl)-1,2,4-triazole (trethbz), 4-(1,2,4-triazol-4-yl)benzoic acid (trPhCO2H), and 3-(1H-imidazol-4-yl)-2-(1,2,4-triazol-4-yl)propionic acid (trhis), were prepared to evaluate their coordination behavior in the development of Mo(VI) oxide organic hybrids. Four compounds, [Mo2O6(trethbz)2]·H2O (1), [Mo4O12(trPhCO2H)2]·0.5H2O (2a), [Mo4O12(trPhCO2H)2]·H2O (2b), and [Mo8O25(trhis)2(trhisH)2]·2H2O (3), were synthesized and characterized. The monofunctional tr-ligand gave a zigzag chain [Mo2O6(trethbz)2] built up from cis-{MoO4N2} octahedra united through common μ2-O vertexes. Employing the heterodonor ligand with tr/-CO2H functions afforded either layer or ribbon structures of corner- or edge-sharing {MoO5N} polyhedra (2a or 2b) stapled by tr-links in axial positions, whereas -CO2H groups remained uncoordinated. The presence of the imidazole-heterocycle as an extra function in trhis facilitated formation of zwitterionic mols. with a protonated imidazolium group (imH+) and a neg. charged -CO2– group, whereas the tr-fragment was left neutral. Under the acidic hydrothermal conditions used, the organic ligand binds to Mo atoms either through [N-N]-tr or through both [N-N]-tr and μ2-CO2– units, which occur in protonated bidentate or zwitterionic tetradentate forms (trhisH+ and trhis, resp.). This leads to a new zigzag subtopol. motif (3) of neg. charged polyoxomolybdate {Mo8O25}n2n- consisting of corner- and edge-sharing cis-{MoO4N2} and {MoO6} octahedra, while the tetradentate zwitterionic trhis species connect these chains into a 2D net. Electronic spectra of the compounds showed optical gaps consistent with semiconducting behavior. The compounds were studied as epoxidation catalysts via the model reactions of achiral and prochiral olefins (cis-cyclooctene and trans-β-methylstyrene) with tert-Bu hydroperoxide. The best-performing catalyst (1) was explored for the epoxidation of other olefins, including biomass-derived Me oleate, Me linoleate, and prochiral DL-limonene. In the experiment, the researchers used many compounds, for example, 4-(4H-1,2,4-Triazol-4-yl)benzoic acid (cas: 157069-48-2Application In Synthesis of 4-(4H-1,2,4-Triazol-4-yl)benzoic acid).
