Abstract
The first 2-aminophosphasilene, [Ar(Me<sub>3</sub>Si)N]HSiPAr′
(<b>4</b>, Ar = 2,6-<i>i</i>Pr<sub>2</sub>C<sub>6</sub>H<sub>3</sub>, Ar′ = 2,6-Mes<sub>2</sub>C<sub>6</sub>H<sub>3</sub>), bearing a hydride ligand on the three-coordinate silicon
atom has been synthesized and structurally characterized. Both X-ray
data of <b>4</b> and DFT calculations on the model compound
(H<sub>2</sub>N)HSiPH (<b>4′</b>) disclosed that
the amino group on the silicon atom results in significant N–Si–P
π conjugation
