Influence of cations in faujasite zeolites in cis-trans isomerization of 4-bromophenyl styryl sulfone

Abstract Cation-exchanged faujasites are used in controlling the photostationary ratio in cis-trans isomerization of 4-bromophenyl styryl sulfone. The predominance of the cis -isomer in zeolites with larger cations is attributed to the smaller cage size.
