ethyl(dimethoxy)phosphane

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 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)

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 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

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Following the procedure of Example 1, 1.5 g (4.14 mmol) of 4-(2-chloro-4-trifluoromethylphenoxy)-1,2-dinitrobenzene, 0.81 g (6.6 mmol) of dimethyl ethylphosphonite and 3 ml of acetonitrile are reacted together to give methyl P-ethyl-2-nitro-5-(2-chloro-4-trifluoromethylphenoxy)phenylphosphinate. are reacted together
