Grignard Synthesis of TriphenylmethanolBackGround Victor Grignard designed a carbon-carbon bond-forming reaction from appropriate alkyl halides and carbonyl compounds without producing alcohol. The Grignard reagent is easily formed by reaction of an alkyl halide, in particular a bromide, with magnesium metal in anhydrous diethyl ether. Although the reaction can be written and thought of as simply  It appears that the structure of the material in solution is rather more complex. There is evidence that dialkylmagnesium is present.BackGround  The Grignard reagent is both a strong base a
