Copper-Catalyzed Hydrogen/Iodine Exchange in Terminal and 1-Iodoalkynes

Detailed kinetic profiles of the copper-catalyzed exchange between the acetylenic proton and iodide of terminal and 1-iodophenylacetylenes are reported. The electronic nature of the alkynes does not influence the equilibrium of the exchange (Keq/sub

Efficient synthesis of 1-iodoalkynes: Via Al2O3 mediated reaction of terminal alkynes and N -iodosuccinimide

Iodination of terminal alkynes using N-iodosuccinimide (NIS) in the presence of γ-Al2O3 was developed to afford 1-iodoalkynes with good to excellent yields (up to 99%). This described approach featured excellent chemoselectivity, good functional group tolerance, and utilization of an inexpensive catalyst.

Reaction of 1-Iodoalkynes with Tin Metal: A New Approach to the Sn–C sp Bond Formation

Abstract: Tin iodoalkynylides were synthesized by the reaction of 1-iodoalkynes with tin metal. The scope of the reaction and the composition of the resulting mixtures were studied. The formation of tin iodoalkynylides was confirmed by counter synthesis v
