Interconversion between a silaimine and an aminosilylene supported by an iminophosphonamide ligand

Abstract

The reaction of a chlorosilylene, supported by an iminophosphonamide ligand, with KN(SiMe₃)₂ resulted in the formation of a silaimine instead of the expected aminosilylene. However, this silaimine exists in equilibrium with the corresponding aminosilylene, which was experimentally demonstrated using variable-temperature NMR spectroscopy and a trapping reaction with elemental selenium to give a silaselenourea.
