F. Kakiuchi et al., Mechanistic study of the Ru(H)(2)(CO)(PPh3)(3)-catalyzed addition of C-H bonds in aromatic esters to olefins, CHEM LETT, (9), 2001, pp. 918-919
The reaction mechanism of the Ru(H)(2)(CO)(PPh3)(3)-catalyzed addition of C
-H bonds in aromatic esters to olefins; was studied by means of deuterium-l
abeling experiments and measurement of the C-13 kinetic isotope effect. The
deuterium-labeling experiment revealed a rapid equilibrium among the inter
mediates prior to the reductive elimination, and the C-13 NMR kinetic isoto
pe effect indicated that C-C bond formation is the rate-determining step in
this reaction.
