Abstract

Oxidative addition of H2 and D2 to the anthracene complex (eta6-AnH)Mo(PMe3)3 giving (eta4-AnH)Mo(PMe3)3X2 (X = H, D) is characterized by a normal equilibrium isotope effect (KH/KD > 1) at temperatures close to ambient; calculations on (eta4-AnH)Mo(PH3)3H2 indicate that this is a consequence of relatively low energy Mo-H vibrational modes.
