Catalytic Insertion of Pd-Vinylidenes Into B─H Bonds.
An unprecedented palladium (Pd)‑catalyzed insertion of unsaturated carbenes into B─H bonds is described. Using alkynyl hypervalent iodine reagents as carbene precursors and amine-borane adducts as boron sources, this method delivers a broad range of E‑configured alkenyl monoborinates in good-to-high yields with excepti...
