A highly efficient additive-dependent chemoselective protocol for the synthesis of fused cyanoarenes and 2-alkynylpyridines has been developed by the reaction of 1,6-diynes with alkynylnitriles using chloro(pentamethylcy ...

An efficient, ruthenium(II)-catalyzed, solvent-free approach for the synthesis of 2-aryloxypyridines with good to excellent yields has been developed by the reaction of 1,6-diynes with aryl cyanates. This atom-economical ...

A new route to synthesize 1-(2-pyridyl)indole scaffolds via the solvent-free, ruthenium(II)-catalyzed, chemo- and regioselective [2+2+2] cycloaddition reaction of diynes with N-cyanoindoles has been developed with good ...
