Abstract
Ruthenium nanoparticles supported on non-cross-linked soluble polystyrene were prepared by reacting [RuCl2(C6H5CO2Et)]2with polystyrene in open air. They effectively catalyze intra-and intermolecular carbenoid insertion into C-H and N-H bonds, alkene cyclopropanation, and ammonium ylide/[2,3]-sigmatropic rearrangement reactions. This supported ruthenium catalyst is much more reactive than [RuCl2(p-cymene)]2and [Ru(Por)CO] for catalytic intermolecular carbenoid C-H bond insertion into saturated alkanes. By using α-diazoacetamide as a substrate for intramolecular carbenoid C-H insertion, the supported ruthenium catalyst can be recovered and reused for ten successive iterations without significant loss of activity.
