乙基磷氮酸二甲酯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of 4-(2-chloro-4-trifluoromethylphenoxy)-1,2-dinitrobenzene (1.6 g, 4.4 mmol), dimethyl ethylphosphonite (1 ml, 8.8 mmol) and acetonitrile (6 ml) is stirred at room temperature overnight. The reaction mixture is concentrated to dryness, and the residue is purified by preparative thin layer chromatography (silica gel, eluting with 10% ethyl acetate/hexane) to give methyl P-ethyl-2-nitro-5-(2-chloro-4-trifluoromethylphenoxy)phenylphosphinate. The reaction mixture is concentrated to dryness the residue is purified by preparative thin layer chromatography (silica gel, eluting with 10% ethyl acetate/hexane)

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Following the procedure of Example 11, 4-(2-nitro-4-trifluoromethylanilino)-1,2-dinitrobenzene and dimethyl ethylphosphonite are reacted together to give methyl P-ethyl-2-nitro-5-(2-nitro-4-trifluoromethylanilino)-phenylphosphinate. are reacted together
