Abstract
n this paper we report the preparation of catalytic membranes having the complex Ru(4-(CF3)TPP)CO (1) (TPP=dianion of tetraphenylporphyrin) embedded in the perfluorinated polymer Hyflon AD60X and their use in the aziridination reaction of olefins by aryl azides. The heterogeneous membrane catalysts afforded high selectivities in aziridine (90-99%). In several cases the membrane was reused three times with a catalyst leaching <= 6% but no decrease in selectivities upon recycle was observed.
