실험 절차

10 g (0.056 moles) of 2,4,4-trimethylpentyl phosphinic acid, 15.82 g (0.056 moles) of methyl oleate (CE-1897 from P&G Chemical) and 0.5 mL (0.0023 moles) of di-tert-amylperoxide are mixed in a 100 mL single neck flask. The mixture is purged with argon to remove oxygen and is heated under argon for 6 hours at 140° C. Tert-amyl alcohol is removed by distillation and 25.8 g (quantitative yield) of 10-[hydroxy-(2,4,4-trimethyl-pentyl)-phosphinoyl]-octadecanoic acid methyl ester is obtained as a slightly yellow oil.
