Abstract
The visible-light-promoted C4-selective phosphorylation of unprefunctionalized pyridine and quinoline derivatives has been accomplished. This Minisci-type protocol provides highly regioselective access to C4-phosphorylation products with good functional group tolerance and moderate to good yields via cross-dehydrogenation coupling under mild conditions. Mechanistic studies have shown that the C4-phosphorylation products are obtained via a radical pathway.
