Process for the preparation of diphenylalkane and diphenylalkane derivatives characterized in that a metal-organic compound of aralkoyl or aryl alcool is made to act on a compound of formula ** in which they represent ryr1 the alkylene radicals and r2 and r3 alkyl radicals are dehydrolyzed the obtained tertiary carbinol metal compound is dehydrated intramolecularly the resulting tertiary carbinol and if necessary hydrogenated the resulting diphenylalkene derivative to obtain the corresponding diphenylalkane derivative being the diphenylalkene derivative and the diphenylalkane derivative capable of being transformed into its salts by conventional salification methods.
