A facile palladium-catalyzed addition/cyclization of (2-hydroxyaryl)boronic acids with alkynylphosphonates has been developed, providing an effective strategy to construct a series of valuable phosphacoumarins. This methodology features excellent regioselectivity and broad substrate tolerance.

Intramolecular hydroarylation using aryl alkynylphosphonates proceeds smoothly with a gold/ silver catalyst in the presence of trifluoromethanesulfonic acid (TfOH) in the 6-endo mode, thus affording a unique synthetic method for phosphacoumarins having various functional groups, which could be a privileged structure and prevalent scaffold in phosphorus heterocycles.
