Intramolecular Cycloadditions of Cyclobutadiene with Olefins [J. Am. Chem. Soc. 2002, 124, 14748-14758]. John Limanto, John A. Tallarico, James R. Porter, Kelli S. Khuong, K. N. Houk,* and Marc L. Snapper* Page 14755, Figure 2. The ∆E+ZPE‡ shown in Figure 2 for cyclobutadiene + ethylene was incorrectly listed as 6.7 kcal/mol. The correct value is 9.2 kcal/mol. Page 14756, Figure 4. The lowest energy conformation for transition structure F is shown below and should replace that given in the paper.
