Switching Over of the Chemoselectivity: I<sub>2</sub>-DMSO-Enabled α,α-Dichlorination of Functionalized Methyl Ketones
Precise control of the chemoselectivity of the halogenation of a substrate equipped with multiple nucleophilic sites is highly demanding and challenging. Most reported chlorinations of methyl ketones show poor compatibility or even exclusive selectivity toward electron-rich arene, olefin, and alkyne residues. This is attributed to the direct or in situ employment of electrophilic Cl2/Cl+ species. Here
