The position of the lithium in the title compound 1 , which formally contains an α‐sulfonyl carbanion, has been clarified by an X‐ray structure analysis: In dimeric 1 the two Li atoms are each coordinated to two O atoms and two N atoms. Consistent with this finding, the C α S distance is extraordinarily short.
