The inside cover picture, provided by Oscar Pàmies, Piet W. N. M. van Leeuwen, Montserrat Diéguez and co‐workers, illustrates that chiral palladium complexes containing phosphite‐oxazoline ligands enable the effective asymmetric intermolecular Heck coupling of several substrates and triflate sources. The kinetic studies and the Hammett plot analysis indicate that the rate‐determining step is the migratory insertion of the alkene. From this finding the authors propose a hypothesis to explain the faster reaction rates of phosphite‐oxazoline systems compared to those of the phosphine analogues.
