Correction to “An Oxidant- and Catalyst-Free Electrooxidative Cross-Coupling Approach to Synthesize meso-Substituted Porphyrin Derivatives”

Abstract

Metrics & MoreArticle Recommendations W e replace the following language, appearing on page 4742: "As reported, the homocoupling of porphyrin was able to be avoided using a large amount of nucleophiles; 6,7 ".The new text should read "As reported, the homocoupling of porphyrin was able to be avoided using a large amount of the nucleophile, 6,7 especially by adding pyridyl moieties to produce pyridinium porphyrins under electrochemical oxidation; 13 ".We also wish to clarify the experimental procedure on page 4745, which states "The mixture was concentrated under reduced pressure." Because the mixture described contains organic chemicals and tetrabutylammonium perchlorate without a note on the hazards associated with perchlorates, we emphasize the need for caution in this operation, especially with respect to avoiding elevated temperatures in the presence of any residual perchlorate salts, and the following note should be added to the procedure: "CAUTION: Perchloroate salts are potentially explosive, and this procedure should be conducted with all due care for working with perchlorate salts, including the avoidance of elevated temperatures."The new ref 13 is as follows:(13) (a) Giraudeau, A.;
