The direct C-H alkynylation of azoles with terminal alkynes proceeds efficiently under a nickel/O(2) catalytic system. On the other hand, a copper/air catalyst enables the coupling of polyfluoroarenes with terminal alkynes. These catalyses provide new accesses to arylacetylenes through the formal direct Sonogashira coupling.
