Electrophilic ipso-iodination of silylated arylboronic acids

Add time:07/20/2019    Source:sciencedirect.com

Silylated functionalized arylboronic acids were converted into corresponding iodinated arylboronic acids in good yields via the electrophilic ipso-desilylation effected with iodine chloride in refluxing CHCl3. Disilylated arylboronic acids were susceptible to diiodination. In addition, the structural characterization and reactivity of a novel sterically hindered ortho-silylated diarylborinic ester were reported. The potential of selected iodinated phenylboronic acids as monomers for the Suzuki–Miyaura cross-coupling polymerization was demonstrated.
