Abstract: The reactions between phthalic anhydrides and primary amines in supercritical CO2 (80–110 bar) to afford the corresponding phthalimides proceed at temperatures of 120–130 °C (aliphatic amines) or 260–275 °C (aromatic amines). The developed procedure fully complies with the principles of green chemistry and allows one to obtain target phthalimides in 65–85% isolated yields, without additional purification and extraction.
Keywords: green synthesis, supercritical carbon dioxide, phthalimides, phthalic ahhydride, amines.
