Crystal cannibalization : In a solution‐mediated single‐crystal‐to‐single‐crystal transition the colorless starting material [{Me 2 N(CH 2 ) 2 OMe}⋅(LiCH 2 SiMe 3 )] 2 converts in toluene into yellow crystals of the benzyllithium tetramer [{Me 2 N(CH 2 ) 2 OMe}⋅(LiCH 2 C 6 H 5 )] 4 (see picture, microscope photograph of the transforming crystals). A straightforward convenient access to commercially interesting benzyllithium in ligand‐stabilized form is thus provided.
