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
