Direct difunctionalization of alkenes with sulfinic acids and NBS leading to β-bromo sulfones
A new and metal-free method has been developed for the synthesis of β-bromo sulfones through the direct difunctionalization of alkenes with sulfinic acids and NBS. This protocol provides a simple, convenient, and efficient approach to various β-bromo sulf
ORGANIC SYNTHESIS WITH SULPHONES - XVII. THE ANTI-MARKOWNIKOFF HALOSULPHONYLATION OF OLEFINS VIA AN IONIC PATHWAY, AND A NEW METHOD OF PREPARING BENZENESULPHONYL IODIDE
Iodine and bromine in the presence of sodium benzenesulphinate react with olefins in acetone solution to give halosulphones resulting from an apparent steric direction of attack at the intermediate halonium ion.A straightforward preparation of benzenesulphonyl iodide from benzenesulphonyl chloride and sodium iodide is also described.
