Herein, we report the application of four amino-tris(phenolate)-based metal complexes incorporating Ti(IV) or Zr(IV) centres (2a-3b) as homogeneous catalysts for conversion CO2 and epoxides into cyclic carbonates. The were synthesised, characterised then evaluated in combination with tetrabutylammonium iodide, bromide chloride binary catalytic systems reaction 1,2-epoxyhexane epoxide substrate ...

Activators regenerated by electron transfer (ARGET) atom radical polymerization (ATRP)-based aqueous miniemulsion where the takes place in stabilized monomer droplets is described. In this work, we compared styrene, n-butyl methacrylate (nBMA) and tert-butyl (tBMA) investigated influence of their hydrophobicity on dispersity, molecular weight particle stability based partition coefficients (log...

Multicomponent reactions are valuable synthetic tools to deliver highly functionalized motifs starting from simple building blocks in only one step and an atom-economical way. Herein we disclose the structure of a new unexpected compound, methyl 5-imino-2-methyl-1,10a-dihydro-5H-chromeno[2,3-b]pyridine-3-carboxylate, which was formed ohmic-heating-assisted multicomponent Hantzsch reaction 3-for...

In this study, a dispersive liquid–liquid microextraction along with back-extraction step (DLLME-BE) has been developed for the determination of thre antidepressant drugs (citalopram, sertraline, and venlafaxine) in biological samples prior to HPLC-UV. Briefly, method involved two main steps: first, deep eutectic solvent (DES) composed tetrabutylammonium bromide (TBABr as agent) 1-dodecanol (as...

In this paper, electrochemical degradation of Reactive Black 5 (RB5) textile azo dye was examined in regard to different synthesis procedures for making PbO2–graphitic carbon nitride (g-C3N4) electrode. The reaction PbOH3- with ClO− the presence surfactants, i.e., cetyltrimethylammonium bromide (CTAB) and tetrabutylammonium phosphate (TBAP), under conventional conditions, resulted formation PbO...

Tosylates and mesylates were directly converted into the corresponding nitroalkanes, by their treatment with tetrabutylammonium nitrite (TBAN) under mild conditions.
