[ 1 ] - Application of SBA-Pr-SO3H as a solid acid nanoreactor in the Biginelli reaction
Sulfonic acid functionalized nanoporous silica (SBA-Pr-SO3H) with a pore size of 6 nm catalyzed three component coupling of aromatic aldehydes, urea and ethyl acetoacetate to afford the corresponding dihydropyrimidinones under solvent free condition. This new protocol for Biginelli reaction has important advantages such as green synthesis, short reaction time, easy isolation and high yields of ...
[ 2 ] - Inhibitive Assessment of N-(8-bromo-3H-phenoxazin-3-ylidene)-N,N’-Dimethylaminium, as a Novel Corrosion Inhibitor for Mild Steel in 1.0 M HCl
The inhibition effect of N-(8-bromo-3H-phenoxazin-3-ylidene)-N,N’-dimethylaminium (DPhDMA) on the corrosion behavior of mild steel in 1.0 M HCl solution has been studied. Weight loss measurements, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and quantum chemical calculations were used in this study. Electrochemical results revealed that DPhDMA is an effective mixed...
[ 3 ] - Synthesis of tetra-substituted phenanthroimidazole derivatives using SBA-Pr-SO3H
A one pot four-component reaction of 9,10-phenanthraquinone, aromatic aldehyde, aniline, and ammonium acetate was designed for the preparation of tetrasubstituted imidazoles (phenanthro[9,10-d]imidazole) derivatives in the presence of SBA-Pr-SO3H as a mesoporous solid acid catalyst. Phenanthro[9,10-d]imidazole derivatives were produced by the use of this technique in short reaction times and go...
