Polydibenzo-18-crown-6-(P-DB-18-C-6), a condensation polymer of dibenzo-18-crown-6 and formaldehyde has ben used as support for borohydride ions in the reduction of few cyclic and acyclic ketones. The reagent has been found to be more stereoselective than dibenzo-18-crown-6-borohydride in the reduction of cyclic ketones. 4-t-butylcyclohexanone has been converted exclusively (100%) to trans-4-t-butylcyclohexanol.
