The N , N -dibenzylcyclam ligand supports a novel double-cyclometallation reaction of zirconium(IV) (R = t Bu, Me, CH2Ph ) in the presence of 4 atm H2 as depicted in Scheme 1 of R. F. Munhá, J. Ballmann, L. F. Veiros, B. O. Patrick, M. D. Fryzuk, Organometallics , 2012 , 31 , 4937.
a. Propose a mechanism for this reaction, which proceeds most slowly for R = CH2Ph , that is consistent with the rate being independent of H2 pressure.
b. Explain the reasoning for your selection. Why might the reaction be slowest with R = CH2Ph )?
