Under analogous conditions, P-halogenoiminophosphanes [X-P=NAr] (X = Cl, Br, I) 3a–c undergo a facile oxidative addition of the P-X bond, forming five-coordinate iminophosphanerhodium(III) complexes of composition [L2Cl(X)Rh(σ-P=BAr)] 5.eninfo:eu-repo/semantics/openAccessIminophosphane , NMR-Spektroskopie540Reactions of iminophosphanes with chlorotris(triphenylphosphine)rhodium(I): generation and NMR identification of the first iminophosphanerhodium(I) and iminophosphanerhodium(III) complexesarticle
