摘要:
The silylmethyl groups of (dialkylaminomethyl)trimethylsilanes 1 undergo ready lithiation with butyl-lithium and the resulting mixtures when quenched with chlorotrimethylsilane or aldehydes afford N,N-dialkyl(2,2,4,4-tetramethyl-2,4-disilapentyl)amines 3 or (dialkylaminomethyl)(2-hydroxyalkyl)-dimethylsilanes 4.
