Reaction Steps

5 g of (+)2 methyl butane 2,3-diol, ##STR24## are mixed with 8.6 g of dichlorophenylphosphin at 0° C. under stirring in 250 ml of dry toluene, in an atmosphere. Then 10.2 g of triethylamine are added within a few minutes. After 1 hour of reaction triethylamine hydrochloride is formed; it is separated by filtration and the toluene solvent is vaporized.
