A mild, efficient, highlyselective, and environmentally friendly oxidation of sulfides to sulfoxides with a recyclable ion-supportedhypervalentiodinereagent has been developed. This reaction is tolerant of hydroxyl, nitrile, methoxy, carbon-carbon double bonds, and ester functionalities. Aliphatic and aromatic sulfides are selectively oxidized to the corresponding sulfoxides at room temperature

Herein, a solution phase NMR conformer population analysis is employed to probe the effect of remote electronic perturbations on the conformationalequilibria of a series of para-substituted β-fluorosulfides (1), sulfoxides (2) and sulfone derivatives (3). Conformations that allow for stabilizing stereoelectronic (σC–H → σ*C–F) and electrostatic (Fδ−…Sδ+) interactions predominate: this is consistent
