Procedure

A solution of 4.75 g (103.2 mmol) of absolute ethanol in 150 ml of absolute n-hexane is added dropwise at 0° C. and while stirring during about half an hour to a solution of 18.24 g (103.2 mmol) of diisobutylaluminum chloride in 150 ml of absolute n-hexane at 0° C. and under a protective gas atmosphere (argon). Thereafter, the temperature of the mixture is allowed to rise to room temperature and the mixture is warmed at about 50° C. for about a further 1 hour to yield the chloro-ethoxy-isobutyl-aluminum starting material.
