The synthesis of nitrofen under microwave irradiation

Objective effect of the yield of nitrofen were synthesized under microwave irradiation.Methods The reactions of p chloro nitrobenzene and phenolates were performed by means of microwave irradiation.Results All the compounds were characterized by elemental analysis,IR,1HNMR and MS. the method has the advantage of high yield, short reaction time and simple in operation.Conclusions microwave irradiation to nucleophilic substitution of arommatic compounds has striking catalystic atction, It shows that the ynthesis of nitrofen were efficient,simple and economical.
