Application

This 2-pyridylsulfinate enables Suzuki-Miyaura cross coupling with aryl halides to access diverse pyridine derivatives as reported by the laboratory of Michael Willis.. No longer impeded by unstable 2-pyridyl boronates, the sulfinate alternatives provide Pd-catalyzed coupling routes to therapeutically valuable pyridine rings.
