Abstract Twenty eight silyl ketimines and several germanium and tin analogs have been prepared by the action of sodium bis (trimethylsilyl) amide on non-enolizable ketones or the reaction of lithium derivatives of ketimines with organosilicon chlorides. Their electronic spectra, the n→ π* transition in particular, have been investigated to the d*-p* interaction between the empty d orbitals of silicon and the π system of the C N bond. The spectral ...
