The syntheses of five alkyldiphenylmethane hydrocarbons, 2-methyldiphenylmethane, 3-methyldiphenylmethane, 2-ethyldiphenylmethane, 4-ethyldiphenylmethane and 4-isopropyldiphenylmethane, are described. The preparation of the hydrocarbons was based on the reaction of the appropriate arylmagnesium halides with benzaldehyde to yield the corresponding alkylbenzhydrols, which are subsequently converted to the hydrocarbons by hydrogenolysis.
