Reaktionsschritte

10 g (0.056 moles) of 2,4,4-trimethylpentyl phosphinic acid, 6.01 g (0.028 moles) of trimethylolpropane diallyl ether and 0.4 mL (0.0019 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 16 g (quantitative yield) of [3-(2-hydroxymethyl-2-{3-[hydroxy-(2,4,4-trimethylpentyl)-phosphinoyl]-propoxymethyl}-butoxy)-propyl]-(2,4,4-trimethylpentyl)-phosphinic acid is obtained as a viscous oil.
