Abstract

Abstract The reaction of aminosilanes Me 4–x Si (NHBu n) x (x= 1–4) with appropriate amounts of n-butyllithium gave the N-lithio derivatives Me 4–x Si (NHBu n) y-(NLiBu n) x–y (x= 1, y= 0 (I); x= 2, y= 0 (II), 1 (III); x= 3, y= 0 (IV), 1 (V), 2 (VI); x= 4, y= 0 (VII), 1 (VIII), 2 (IX), 3 (X)). Their infrared and 1 H NMR spectra are reported, along with the 7 Li NMR spectra of solutions of compounds I–IV and their complexes with PMDETA or TMEDA in n-pentane, ...
