Two (aminomethyl)(lithiomethyl)silanes Ph2Si(CH2Li)(CH2NC5H10) (NC5H10 = 1-piperidinyl) (2) and Me2Si[R][CHLiPh]}(CH2SMP) SMP = 1-[(S)-2-(methoxymethyl)pyrrolidinyl]I [(R,S)-17] are presented including their solid state structures, the first one non-chiral, the latter highly diastereomerically enriched. By metathesis reactions with metal(II) halides (metal = Mg, Ga, Pd, Cd and Hg), the corresponding bis[(aminomethyl)silyl]methyl}metal(II) compounds or the [(aminomethyl)silyl]methylmetal(II) halides were obtained. In the case of highly diastereornerically enriched (aminomethyl)(lithiomethyl)silane (R,S)-17, the 'carbanionic' fragment could be transferred with high stereoselectivities on the metals Hg and Pd. For all of the compounds, the solid state molecular structures were determined. (C) 2002 Published by Elsevier Science B.V.
