Synthesis, characterization and fluorescence studies of novel bi-phenyl based acrylate and methacrylate

Synthesized photo-cross-linking chalcones as novel corrosion inhibitors for mild steel in acidic medium: experimental, quantum chemical and Monte Carlo simulation studies

“…The synthesis of the chalcone derivatives was carried out as previously reported. 17,24 A mixture of 4-hydroxybenzaldehyde (0.015 mol) and 4-methylacetophenone (0.015 mol) was put in 30 mL methanol aer which potassium hydroxide (40%, 20 mL) was added slowly with constant stirring. Aer 6 h the reaction mixture was poured in ice cold water (500 mL) to obtain a yellow precipitate.…”

“…The chalcone derivatives also showed two doublets at 7.42 (d, J ¼ 15.5 Hz, 1H) and 7.78 (d, J ¼ 15.5 Hz, 1H) ppm which are known to be characteristic peaks of chalcone moiety with the coupling constant (J) values that conrm the synthesized chalcones as trans isomers. 24…”

Benzimidazole‐indole‐chalcone connected methacrylate‐based side chain D‐π‐A polymer and its application in organic photovoltaics

“…A double‐necked flask was charged with a mixture of a compound 3a (2 g, 0.003 mol) dissolved in dry DCM and treated with freshly distilled acryloyl chloride (0.3 mL, 0.003 mol) in the presence of triethylamine, at 0 to 5 °C. The above mixture was stirred at room temperature in the presence of nitrogen atmosphere for 2 h . The quaternary ammonium salt was filtered and the reaction mixture separated using excess of DCM.…”

Synthesis, Characterization, and Electrochemical Studies of Novel Biphenyl Based Compounds

“…Inhibitor (BOH) was prepared as described in the literature. 11 4-Acetylbiphenyl (10.2 mmol) was added (30 mL) with potassium hydroxide (0.0408 mol) in methanol. To the above reaction mixture, 4-hydroxybenzaldehyde (10.2 mmol) in 10 mL of methanol was added dropwise with constant stirring at 60 °C.…”
