2-Hydro-2-aminophosphasilene with N–Si–P π Conjugation
摘要:
The first 2-aminophosphasilene, [Ar(Me3Si)-N]HSi=PAr' (4, Ar = 2,6-iPr(2)C(6)H(3), Ar' = 2,6-Mes(2)C(6)H(3)), bearing a hydride ligand on the three-coordinate silicon atom has been synthesized and structurally characterized. Both X-ray data of 4 and DFT calculations on the model compound (H2N)HSi=PH (4') disclosed that the amino group on the silicon atom results in significant N-Si-P pi conjugation.

are incompatible with many functional groups. In particular, unsaturated functionalities are not tolerated owing to their facile reaction with low‐coordinate germanium compounds. We now report the synthesis of an imino‐functionalized germanium(II) species, stabilized by coordination of an N‐heterocyclic carbene (NHC), by reaction of an isonitrile with a heavier NHC‐coordinated vinylidene.
