Extremely high trans selectivity of Ti-MWW in epoxidation of alkenes with hydrogen peroxide

A novel titanosilicate with MWW topology, Ti-MWW, exhibits a behavior not observed on other titanosilicates such as TS-1, TS-2 and Ti-beta, in that it selectively epoxidizes trans isomers from a mixture of cis/trans alkenes with retention of stereochemistry.
