Olefins, Grignard reagents, titanium

Of the aforementioned transition metal-catalyzed Grignard exchange reactions, the most standard method that has the broadest applications in organic synthesis is perhaps a titanium-catalyzed hydromagnesation of olefins and acetylenes with low molecular weight Grignard reagents. 

Other applications of titanium catalysts are hydromagnesation and carbomagnesation of unsaturated compounds, such as olefins and acetylenes with Grignard reagents. These are described in Chapter 3. 

Olefins can be used for Grignard synthesis when they are exchanged with an easily available Grignard reagent in the presence of titanium tetrachloride A simple synthesis of a,/5-dialkyl-acrylates through an oxalic ester condensation product has been reported...
