Abstract: The invention comprises titanium tetramethy, which is prepared by reacting a compound of formula TiZ4, where Z is halogen or an alkoxy group with a methyl compound of an alkali metal, an alkaline-earth metal, beryllium or magnesium at a temperature below about 0 DEG C. Preferred alkoxy groups are those containing 1-4 carbon atoms. The preferred metal methyls are lithium methyl, magnesium dimethyl and magnesium methyl halides. The reaction is carried out in the absence of air and moisture preferably in an ether solvent such as dimethyl, diethyl, dipropyl, diisopropyl, or dibutyl ether, tetrahydrofuran or dioxane. Titanium tetramethyl reacts with carbonly compounds such as aldehydes and ketones to yield an alcohol thus
