Pure α-Metallated Benzyllithium from a Single-Crystal-to-Single-Crystal Transition

Crystal cannibalization: In a solution‐mediated single‐crystal‐to‐single‐crystal transition the colorless starting material [{Me2N(CH2)2OMe}⋅(LiCH2SiMe3)]2 converts in toluene into yellow crystals of the benzyllithium tetramer [{Me2N(CH2)2OMe}⋅(LiCH2C6H5)]4 (see picture, microscope photograph of the...

Description
Summary:Crystal cannibalization: In a solution‐mediated single‐crystal‐to‐single‐crystal transition the colorless starting material [{Me2N(CH2)2OMe}⋅(LiCH2SiMe3)]2 converts in toluene into yellow crystals of the benzyllithium tetramer [{Me2N(CH2)2OMe}⋅(LiCH2C6H5)]4 (see picture, microscope photograph of the transforming crystals). A straightforward convenient access to commercially interesting benzyllithium in ligand‐stabilized form is thus provided.
