Abstract

The reaction mechanism of the Ru(H)₂(CO)(PPh,₃)₃-catalyzed addition of C-H bonds in aromatic esters to olefins was studied by means of deuterium-labeling experiments and measurement of the ¹³C kinetic isotope effect. The deuterium-labeling experiment revealed a rapid equilibrium among the intermediates prior to the reductive elimination, and the ¹³C NMR kinetic isotope effect indicated that C-C bond formation is the rate-determining step in this reaction.
