【Abstract】 A series of new N-pyrazolinyl-α-aminophosphonates were synthesized by the addition of diethyl phosphite and benzyl-iminoantipyrine.Their structures were confirmed by IR,MS, 1H NMR and elementary analysis,The differences of two ethyloxyl groups in 1H NMR was discussed. The preliminary bioassay shows that some of them have a good antivirus activity on plants.更多还原
