Graphical Abstract

In order to finally resolve the controversy over the structure of α-lithiated sulfones and α-sulfonyl carbanions, MeSO2Ph was lithiated in TMEDA and the product, the title compound, was studied by X-ray analysis. It is a dimer in which the Li, S, and O atoms form a flat eight-membered ring. The nearly planar CH2S group lies outside the coordination sphere of Li.
