Green and Efficient One-Pot Synthesis of 2-Amino-3-phenylsulphonyl-4H-chromenes under Solvent-Free Conditions
A green and convenient method for the synthesis of 2-amino-3-phenylsulphonyl-4H-chromenes by a one-pot three-component condensation of 1-naphthol, phenylsulphonylacetonitrile and aromatic aldehydes under solvent-free conditions using potassium phosphate tribasic trihydrate as an efficient catalyst is described. The reaction of 1-naphthol with phenylsulphonylacetonitrile and various aromatic...
متن کاملPolymer/HIO4 : An efficient catalyst for solvent-free synthesis of 2-naphthol azo dyes
A convenient, one-pot method for the synthesis of diazonium salt has been developed by the sequential diazotization of aromatic amines with NaNO2, polymer- supported periodic acid (PPIA) and 2-naphthole under solvent-free conditions at room temperature. By using this method, several types of aromatic amine, containing electron-withdrawing and electron-donating groups, were rapidly converted to ...
متن کاملCharacterization and Application of SO3H-functionalized Phthalimide (SFP) as an Efficient and Recyclable Catalyst for the Solvent-free Synthesis of 2-Amino-4H-chromenes
In this research, SO3H-functionalizedphthalimide (SFP) has been prepared through simple reaction of phthalimide with chlorosulfonic acid, and characterized using FT-IR, 1H NMR, 13C NMR, SEM (scanning electron microscopy), mass and TG (thermal gravimetric) spectra. Afterward, the solid acid has been utilized as an efficient, green, heterogeneous and recyclable ca...
