title: 1,1-Dibromo-1-alkenes as valuable partners in the copper-catalyzed direct alkynylation of azoles.
abstract: The copper-catalyzed direct alkynylation of azoles with 1,1-dibromo-1-alkenes as electrophiles is described. These easily accessible substrates are a useful addition to the field of direct alkynylations in an efficient and functional group tolerant reaction to provide a straightforward entry to diverse alkynyl heterocycles.
