Reaction of hydroxylated heteroarenes and acetylene in the presence of SnCl4 and Bu3N (or Et3N) gives the corresponding ethenylated arenes. The reaction takes place at the neighboring position of the hydroxy group, and is applicable to quinolines, an isoquinoline, pyridines, and N-trifluoromethanesulfonylated indoles provided that the optimized conditions for the ethenylation and workup are employed.
