Epoxide-Opening and Group-Transfer Reactions Mediated by Monomeric Zirconium Imido Complexes [J. Am. Chem. Soc. 2003, 125, 14276-14277]. Suzanne A. Blum, Patrick J. Walsh, and Robert G. Bergman* Page 14277. It has come to our attention that the first-order rate constants, which we reported as s-1, were actually recorded as min-1. This translates into a corrected value of ∆Sq ) -18 ( 4 cal mol-1 K-1. We thank Dr. Forrest E. Michael for bringing this to our attention. Additionally, we have realized that we neglected to discuss the fact that the known (referenced) ∆Sq values for acid-assisted ring opening refer to values in the polar solvent H2O, which is highly ordered in the ground state, and therefore may not be applicable to the reaction in our paper, which was carried out in toluene. We regret these mistakes. JA0408146 10.1021/ja0408146 Published on Web 07/02/2004
