Procedure

152 g (1 mol) of 2-(ethylhydroxyphosphinyl)acetic acid (produced as in Example 11) and 170 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 167 g (96% of theory) of 2-(ethylhydroxyphosphinyl)acetic acid titanium salt.
