Abstract
A series of (hydridosilyl)hydrazines 1 - 12 has been prepared from the corresponding chloro- or bromosilanes and hydrazines in the presence of triethylamine as an auxiliary base. Methylsilyl (MeH2Si-), dimethylsilyl (Me2HSi-), and phenylsilyl (PhH2Si-) groups have been introduced as substituents. NMR spectra (H-1, C-13, N-15, Si-29) have been measured and used to determine the rotation barrier about the N-N bond in (PhH2Si)(Me2HSi)N - N(SiHMe2) (9), which has been found to be 75 kJmol-1. The crystal structure of (PhH2Si)2N - N(SiH2Ph)2 (7) features each of the two NNSi2 groups as nearly planar, but with a dihedral angle close to orthogonal. Such a structure is also implied for 9 on the basis of the NMR spectra.
