The reaction between 1 and 5-substituted (Z)-2-methyl-2-en-4-ynoic acids provides a mixture of 6-substituted 5-iodo-3-methyl-2H-pyran-2-ones and (E)-3-methyl-5-ylidene-5H-furan-2-ones in which these last compounds are the minor components (see: ref 10).

This assignment supports the formation of a cyclic iodonium intermediate similar to that previously proposed for the electrophilic addition of I-X species to dialkyl acetylenes [Bassi, P.; Tonellato, U. J. Chem. Soc., Perkin Trans. 2 1973, 669].

The regiochemistry of 6, which was assigned on the basis of a principle similar to that used to establish the structures of 5a-d, proved to be in agreement with that of the products of the reaction of 1 either with alkylethynes in acetonitrile (see ref 4) or with ethyl 3-butynoate in CC14, AcOEt, AcOH, or EtCOOH solution (see ref 3).

The chemical shifts of acetylenic carbon atoms have already been used as an appoximative measure of the zonal charge density [Meier, H.; Stavidrou, E.; Storek, C. Angew. Chem., Int. Ed. Engl. 1986, 25, 809. Rosenberg, D.; Drenth, W. Tetrahedron 1971, 27, 3893].
