Publisher Correction: Visible light-driven conjunctive olefination (Nature Chemistry, (2022), 14, 1, (66-70), 10.1038/s41557-021-00807-x) (2021)
Journal Article
Filippini, D., & Silvi, M. (2021). Publisher Correction: Visible light-driven conjunctive olefination (Nature Chemistry, (2022), 14, 1, (66-70), 10.1038/s41557-021-00807-x). Nature Chemistry, 14(1), Article 110. https://doi.org/10.1038/s41557-021-00863-3

In the version of the article originally published, there was an error in Fig. 2d. Specifically, the first instance of what now reads as “PPh3Br” initially appeared as “PPh3BrH.” This has been corrected in the online version of the article.

Carboxylic acids and aldehydes are ubiquitous in chemistry and are native functionalities in many bioactive molecules and natural products. As such, a general cross-coupling process that involves these partners would open new avenues to achieve molec... Read More about Visible light-driven conjunctive olefination.

Visible?Light?Driven Strain?Increase Ring Contraction Allows the Synthesis of Cyclobutyl Boronic Esters (2020)

Radical Addition to Strained σ-Bonds Enables the Stereocontrolled Synthesis of Cyclobutyl Boronic Esters (2019)
Journal Article

While radical additions to π-bonds are well established, additions to σ-bonds are far less explored. We have found that electron deficient radicals derived from alkyl iodides under visible light irradiation add to the central strained bond of bicyclo...
