Synthesis of acetylene-substituted indoles and benzofuranes was performed by reaction of polyiodoanilines and polyiodophenols with phenylacetylene in the presence of palladium catalyst.

Reactions of Alkynes with Iodine and Potassium Iodide in AceticAcid in the Presence of Nitrates. Simple Synthesis of 1-Iodo-2nitroalkenes.-Reaction of aryl-and alkylacetylenes with iodine (or potassium iodide) and nitrates proceeds at the acetylene moiety to furnish viciodonitroalkenes. Side products are diiodoalkenes as well as acetoxyiodoalkenes. The influence of reaction conditions and acetylene substitution on the reaction outcome is studied. A possible reaction mechanism, involving addition of in situ generated INO 2 to the acetylene, is discussed. -(YUSUBOV, M. S.; PEREDERINA, I. A.; KULMANAKOVA, YU. YU.; FILIMONOV, V.
