Procedure

166 g (1 mol) of ethyl(2-methyl-3-hydroxypropyl)phosphinic acid (produced as in Example 13) and 85 g of titanium tetrabutoxide are refluxed in 500 ml of toluene for 40 hours. The resulting butanol is distilled off from time to time with proportions of toluene. The solution formed is subsequently freed of solvent to leave 161 g (91% of theory) of ethyl(2-methyl-3-hydroxypropyl)phosphinic acid titanium salt.
