reaction of alkyl sulfinates with alkynyl(aryl)iodonium
salts provides a facile access into otherwise difficult to obtain
alkyl alkynyl sulfones and cyclic vinyl sulfones via 1,2-rearrangement
or 1,5-CH insertion, respectively. In benzyl sulfinates, 1,5-CH insertion
is not possible, so addition to the aromatic ring occurs, followed
by ring expansion to generate novel bicyclic sulfones.
