A straightforward regio- and diastereoselective process has been developed for the synthesis of unprecedented symmetrical trans-α,α′-bis(diphenylphosphoryl)- and α,α′-bis(diphenylphosphorothioyl)-cycloalkanones, through the reaction of cyclic enamines with excess P-chlorodiphenylphosphine in the presence of triethylamine, followed by oxidation or sulfurization and hydrolytic workup.
