実験手順

6.31 g (0.0354 moles) of 2,4,4-trimethylpentyl phosphinic acid, 10 g (0.0354 moles) of oleic acid and 0.25 mL (0.0012 moles) of di-tert-amylperoxide are mixed in a 50 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 13.5 g (83% yield) of 10-[hydroxy-(2,4,4-trimethyl-pentyl)-phosphinoyl]-octadecanoic acid is obtained as a viscous oil.
