Alternate lithiation and reaction with ClSiMe3 of 2,6-dimethylpyridine gave the lithium derivatives of pyridine substituted at the 2- and 6-positions by mono- or bis(trimethylsilyl)methyl groups. The relative ease of formation of these compounds is discussed and compared to their reactivity with transition metal halides. The reaction of NiCl2 with the lithium derivative of bis(trimethylsilyl)methylpyridine gives the remarkably air-stable nickel(II) alkyl bis[C,N-2-pyridylbis(trimethylsilyl)methyl]nickel(II).
