hydrocarbons is described that proceeds under practical, scalable and mild conditions. Sulfonyl halides featuring aryl, heteroaryl and alkyl substituents are generated in situ from sulfinate salts and convenient halogen atom sources. This chemistry enables the synthesis of an array of halogen/sulfonyl-substituted bioisosteres and cyclobutanes, on up to multidecagram scale. Hal=Halogen.

A highly regioselective iodosulfonylation of allenes in the presence of CuI and 1,10-phenanthroline has been developed for the synthesis of various useful (E)-α-iodomethyl vinylsulfones in moderate to excellent yields. This practical reaction is fast, operationally simple, and in particular, proceeds under very mild conditions to afford the target products with high regio- and stereoselectivity. The
