Abstract The N-hydroxyphthalimide derivatives, F 15-and F 17-NHPI, bearing a long fluorinated alkyl chain, were prepared and their catalytic performances were compared with that of the parent compound, N-hydroxyphthalimide (NHPI). The oxidation of cyclohexane under 10 atm of air in the presence of fluorinated F 15-or F 17-NHPI, cobalt diacetate [Co (OAc) 2], and manganese diacetate [Mn (OAc) 2] without any solvent at 100 C afforded a ...
