title: Metal-Free Oxidative Radical Alkynylation/Ring Expansion Rearrangement of Alkenyl Cyclobutanols with Ethynylbenziodoxolones.
abstract: The first metal-free alkynylation/ring expansion cascade process of alkenyl cyclobutanols with ethynylbenziodoxolones has been developed. A variety of synthetically valuable β-alkynylated cyclopentanones were prepared in moderate to good yields. Alkynyl cyclobutanols could also undergo this transformation, providing a new approach to substituted ene-yne-carbonyl compounds.
