The
factors affecting the stabilization of diphosphastannylenes,
such as substituent size, steric demand, and type of substituent (aryl,
alkyl, silyl) were investigated via a comprehensive DFT and experimental
investigation. The influence of various substituents (H, Me, tBu, Ph, TMS, Hyp = (Si(SiMe3)3)) on
the pyramidalization of the phosphorus centers and cone angle determination
of those substituents were carried out. Through these considerations,
ligand systems capable of isolating a stable Sn(II) species were determined.
Synthetic work led to the isolation of dimeric supermesityl(trimethylsily)phosphanides,
2,4,6-tris(t-butyl)phenyl trimethylsilyl lithium
phosphanide, 2,4,6-tris(t-butyl)phenyl trimethylsilyl
potassium phosphanide, and one hypersilylphosphanide [HypP(SiMe3)K·DME]. In addition to that, a novel monomeric diphosphastannylene
[HypP(SiMe3)]2Sn was isolated as well as confirmed
by experimental and calculated NMR data and single crystal X-ray analysis.
