Mechanism of the Kulinkovich Reaction. If ethylmagnesium bromide is used, the formation of ethane and a trace of ethene can be observed. Two equivalents of the Grignard reagent react with titanium(IV) isopropoxide to give a thermally unstable diethyltitanium compound, which rapidly undergoes β-hydride elimination with the loss of ethane to yield the substituted …
