Dendronized polyamides supports for Mo catalysts

Dendronized polyamides of generations 1 and 2 were grafted with ethylenediamine (en) ligands at their peripheries by the condensation of chloromethyl groups and en molecules. The obtained dendronized complexes were further equipped with MoO2acac2 to form the catalysts PGn-en-Mo. The results of FT-IR and thiocyanate photometric analysis confirmed the successful immobilization of Mo catalysts on dendronized polyamides. The catalytic properties of PGn-en-Mo were first studied in the epoxidation of cyclohexene with tert-butyl hydroperoxide and exhibited high catalytic activity and selectivity. © 2012 Wiley Periodicals, Inc.
