Correction to “Cyclopropanation with Gold(I) Carbenes by Retro-Buchner Reaction from Cycloheptatrienes” César R. Solorio-Alvarado, Yahui Wang, and A. M. Echavarren* J. Am. Chem. Soc. 2011, 133, 11952−11955. DOI: 10.1021/ja205046h Page 11953. In Chart 1, the configuration assigned for the major isomer should be reversed from trans to cis for cyclopropanes 4m−r,t−v and 4aa, and from exo to endo for
tetrahydrocyclopropa[a]indenes 4ab−ad. We thank Dr. Philipp Holstein for this configurational reassignment. The corrected Chart 1 is shown here.
