The reaction proceeds with high atom efficiency most likely through an alkynyl-episulfonium intermediate. The transformation is copper-catalyzed and compatible with a large array of thiiranes and thietanes.Chemistry, OrganicChemistryring-opening reactionsalkynylationepoxidesoxetanesepisulfidesderivativesefficientsulfidesindolethiolsCopper-Catalyzed Oxyalkynylation of C-S Bonds in Thiiranes and Thiethanes with Hypervalent Iodine Reagentstext::journal::journal article::research article
