Cp*Rh(III)-catalyzed C-H bond amidation proceeding by an intramolecular amide transfer in N-phenoxyacetamide derivatives. Combining experimental and theoretical studies, we propose that the olefin promotes a Rh(III) intermediate to undergo oxidative addition into the O-N bond to form a Rh(V) nitrenoid species and subsequently direct the nitrenoid to add to the ortho position. The amidedirecting group plays a dual

A method of crosslinking an oxidative polymer having oxidatively crosslinkable functional groups and a two-pack composition used therein. The oxidatively crosslinkable functional groups on the oxidative polymer are crosslinked by contacting the oxidative polymer with a catalytic amount of an oxidizing enzyme, such as horseradish peroxidase. The present invention is further directed to a two-pack coating composition which includes a polymeric component and a catalytic component, which are mixed together prior to use.
