Benzene, 2-chloro-1-(3,4-dinitrophenoxy)-4-(trifluoromethyl)- → HCID 178526694, compound

Participants

Reaction Steps

A mixture of 4-(2-chloro-4-trifluoromethylphenoxy)-1,2-dinitrobenzene (1.8 g, 4.97 mmol), sodium hypophosphite (0.88 g, 9.94 mmol) and cupric sulfate (180 mg) in 20 ml of methyl nitrile/water (4:1) is heated under reflux for 24 hours. The reaction is poured into water, extracted with methylene chloride, dried and chromatographed (silica gel, eluting with 10% methanol/chloroform) to yield 2-nitro-5-(2-chloro-4-trifluoromethylphenoxy)phenylphosphinic acid.
