Synthesis and Structure of a Unique Monomeric σ‐Bonded Aryllithium Compound Stabilized by a Weak Li—Benzene π Interaction

Stabilized only by steric effects and weak solvation by benzene, the aryllithium compound 1 exists as a monomeric benzene adduct. The unique structure of 1 in the solid state is shown on the right; the ortho substituents on the η1-bound phenyl ring have been omitted for clarity.
