5 g (0.028 moles) of 2,4,4-trimethylpentyl phosphinic acid, 4.78 g (0.28 moles) of 10-undecen-1-ol and 0.3 mL (0.0014 moles) of di-tert-amylperoxide is mixed in a 50 mL single neck flask. The mixture is purged with argon to remove oxygen and is heated under argon for 5 hours at 140° C. Tert-amyl alcohol is removed by distillation and 9.8 g (quantitative yield) of (11-hydroxy-undecyl)-(2,4,4-trimethylpentyl)-phosphinic acid is obtained as a viscous oil.
