Application of 0.5 equivalent of methyl formate to diphenylcarbinolmagnesium iodide formed by the Grignard reaction results in the formation of diphenylmethyl ether, (C6H5)2CH-O-CH(C6H5)2. Use of an excess of methyl formate affords diphenylmethyl iodide, which was proved indirectly by the formation of sym-tetraphenylethane with magnesium. Formation of diarylacetic acid from the diarylmethyl iodide here formed was attempted. Application of magnesium would give a hydrocarbon and will not form a Grignard reagent. Therefore, carbon dioxide gas was passed through during the addition of magnesium and the objective acid was obtained in a small amount.
