ZnO Nanopowder: An Efficient Catalyst for the Preparation of 2,4,6-Triaryl Pyridines under Solvent-Free Condition

Environmentally Benign Water-Soluble Sodium L-2-(1-Imidazolyl) Alkanoic Acids as New Corrosion Inhibitors for Mild Steel in Artificial Seawater

“…Besides, the electrochemical results reveal that IZSs may interact with the dissolved iron and adsorbed inhibitor molecules in corrosive solution, resulting in poor or negative inhibition performance at lower and higher inhibitor concentrations (Figure ). The poor inhibition efficiency at lower and higher inhibitor concentrations may be due to higher conductivity of inhibitor solution; see Figure S9 . Combining all results, it can be concluded that the inhibitor molecule has competitive interaction between the metal surface and dissolved ions (iron and inhibitor).…”

Efficient synthesis of symmetrically substituted pyridines and substituted alkenes through green and heterogeneous catalysis with zinc phosphate

“…21 In 2020, zinc oxide (ZnO) was applied as a catalytic support in the synthesis of triarylpyridine derivatives. 22 Recently, various catalysts were used to synthesize trisubstituted pyridine derivatives such as graphene oxide (GO), 5 tert-Butylate de potassium ( t -BuOK/DMSO), 23 Fe 3 O 4 @THAM-SO 3 H, 24 titania-supported triflic acid 25 and [ t -Bu 2 Sn(OH)(H 2 O)] 2 2+ 2OTf − . 26 Nonetheless, these methods have significant drawbacks, including the use of toxic solvents and homogeneous catalysts and the high costs associated with their preparation and recycling.…”

One-pot, solvent-free and efficient synthesis of 2,4,6-triarylpyridines catalyzed by nano-titania-supported sulfonic acid as a novel heterogeneous nanocatalyst

“…Recently, the synthetic approach to 2,4,6-triarylpyridines involves cyclo-condensation reaction of acetophenones, benzaldehydes and ammonium acetate in the presence of different catalysts under heating condition or sonication and microwave irradiation [18][19][20][21][22].…”
