A highly selective synthesis of 2-aryl-1-arylmethyl-1H-1,3-benzimidazoles from the reaction of o-phenylenediamine and aromatic aldehydes in the presence of sulfuric acid {[3-（3-silicapropyl）sulfanyl]propyl}ester（SA...A highly selective synthesis of 2-aryl-1-arylmethyl-1H-1,3-benzimidazoles from the reaction of o-phenylenediamine and aromatic aldehydes in the presence of sulfuric acid {[3-（3-silicapropyl）sulfanyl]propyl}ester（SASPSPE） in water and at 80℃in good to excellent yields.展开更多
A simple, efficient and low-cost methodology for the synthesis of α-aryl-α,β-unsaturated esters using paraformaldehyde as a source of carbon was developed. Factors that control reaction yields such as temperature, ...A simple, efficient and low-cost methodology for the synthesis of α-aryl-α,β-unsaturated esters using paraformaldehyde as a source of carbon was developed. Factors that control reaction yields such as temperature, concentration and reaction time were evaluated. A mechanism is proposed based on experimental structures of the intermediates.展开更多
