Reaction Steps

To a solution of methyl P-methyl-2-cyano-5-(2-chloro-4-trifluoromethylphenoxy)-phenylphosphinate (0.46 g) in 10 ml of methylene chloride is added trimethylsilyl bromide (0.75 ml) dropwise. The mixture is stirred for 2 hours, after which methanol is added. The reaction is stripped and evaporated under vacuum to give P-methyl-2-cyano-5-(2-chloro-4-trifluoromethyl-phenoxy)phenylphosphinic acid, m/s 375 (M+).
