(DHPMs) via dehydrosulfurative Sonogashira cross-coupling with concomitant oxidative dehydrogenation using a Pd/Cu catalytic system. Together with the ready availability of DHPMs possessing various substituents at the C4–C6 positions, this transformation offers rapid and general access to diverse 2-alkynylpyrimidine derivatives.
