A four‐membered chelate ring (O, S, C, Ti) is present in the structure of crystalline 1 ; this indicates that the Ti atom is bonded via the “carbanion”‐C atom and one O atom of the sulfonyl group to the deprotonated sulfone. According to NMR results, 1 also exists in solution as an organotitanium compound.
