Colorimetric quantification of α-tocopherol (vitamin E) in pure form and different comestible samples by using newly synthesized tetrazolium salts

A quick, susceptible, and viable spectrophotometric procedure for the assay of α-tocopherol by newly synthesized tetrazolium reagents 2-phenyl-3-(2-thiazolyl)-5-(4-methoxyphenyl)tetrazolium bromide (PTMPT) and 2-phenyl-3-(2-thiazolyl)-5-(4-nitrophenyl)tet

Synthesis of 1,1′-([1,1′-Biphenyl]-4,4′-diyl)bis(3-aryl-5-phenylformazans) and 1,1′-([1,1′-Biphenyl]-4,4′-diyl)bis(3-aryl-5-phenyl-5,6-dihydro-1,2,4,5-tetrazin-1-ium) Perchlorates

Abstract: New bis-formazans and bis(5,6-dihydro-1,2,4,5-tetrazin-1-ium) perchlorates were synthesized with high yields under mild conditions. 1,1′-([1,1′-Biphenyl]-4,4′-diyl)bis(3-aryl-5-phenylformazans) were obtained by diazo coupling of para-substituted benzaldehyde phenylhydrazones with [1,1′-biphenyl]-4,4′-bis(diazonium chloride). Treatment of the obtained bis-formazans with formaldehyde in the presence of perchloric acid in dioxane afforded 1,1′-([1,1′-biphenyl]-4,4′-diyl)bis(3-aryl-5-phenyl-5,6-dihydro-1,2,4,5-tetrazin-1-ium) diper-chlorates. The structure of the synthesized compounds was confirmed by elemental analyses and UV, IR, and 1H and 13C NMR spectra.

Indoline Catalyzed Acylhydrazone/Oxime Condensation under Neutral Aqueous Conditions

Acylhydrazones formation has been widely applied in materials science and biolabeling. However, their sluggish condensation rate under neutral conditions limits its application. Herein, indolines with electron-donating groups are reported as a new catalyst scaffold, which can catalyze acylhydrazone, hydrazone, and oxime formation via an iminium ion intermediate. This new type of catalyst showed up to 15-fold rate enhancement over the traditional anilinecatalyzed reaction at neutral conditions. The identified indoline catalyst was successfully applied in hydrogel formation.
