Direct dehydrative cross-coupling of tautomerizable heterocycles with alkynes via Pd/Cu-catalyzed phosphonium coupling

The first chemoselective direct dehydrative cross-coupling of tautomerizable heterocycles with alkynes has been achieved via C-H/C-OH bond activations with direct C(sp2)-C(sp) bond formation, which is in line with ideal synthesis using readily

Synthesis of thieno[2,3-b]quinoxalines from 2-haloquinoxalines

Thieno[2,3-b]quinoxalines were synthesized from 2-haloquinoxalines using palladium catalyst. The coupling of latter with alkynes and addition of one mol equivalent of bromine to the 2-alkynylquinoxalines thus produced was described. The resulting dibromid
