Unexpected rate retardation in the formation of phthalic anhydride from N-Methylphthalamic Acid in acidic H2O-CH3CN medium
Kinetic study on the cleavage of N-methylphthalamic acid (NMPA) in mixed acidic aqueous-acetonitrile solvent reveals the formation of both phthalic anhydride (PAn) (through O-cyclization) and N-methylphthalimide (NMPT) (through N-cyclization). The formation of NMPT varies from similar to 20% to simi...
