Synthesis of G3: In a 50 mL round bottom flask containing 5 mL of DMF, 2a (0.5 mmol, 137.5 mg) and 4-nitro-3-aminophenol (1 mmol, 154.1 mg) were added followed by 100 μL of thionyl chloride via a syringe. The solution was stirred at room temperature for 5 min and then quenched...
Yang and coauthors [83] developed a sustainable technique for the production of 2-substituted BTs using mesoporous poly (melamine–formaldehyde) as an eco-friendly, heterogeneous organocatalyst (Scheme 14). The authors also discovered that 10 mg of mPMF, xylene as a solvent, and a temperature ...
