Versuchsvorschrift

A mixture of 4-(2-chloro-4-trifluoromethylphenoxy)-1,2-dinitrobenzene, (2-chloro-α,α,α-trifluoro-p-tolyl-3,4-dinitrophenyl ether) (1.2 g, 3.31 mmol) and dimethyl methylphosphonite (0.57 g, 5.3 mmol) in 3 ml of acetonitrile is refluxed overnight. The mixture is concentrated and the residue is purified by column chromatography (silica gel, eluting with 3% ethyl acetate/hexane) to yield methyl P-methyl-2-nitro-5-(2-chloro-4-trifluoromethylphenoxy)phenylphosphinate.
