Quantum-Chemical Calculations of NMR Chemical Shifts of Organic Molecules: IX. Electronic Structure of [Dimethylamino(chloro)methylideneamino] trichloro- phosphonium Hexachlorophosphate: Azomethine or Azophosphine?

摘要

Relying on the study of the electronic structure of [dimethylamino(chloro)methylideneamino] trichlorophosphonium hexachlorophosphate by means of ~(31)P NMR and quantum chemistry it was shown that in chloroform this substance existed as trichlorophosphazo compound with a positive charge localized on the dialkylimino group.
