Insertion of a phosphorus atom into zirconium–methyl bonds , and migration of a chlorine atom to the metal center—the reaction of the chloroiminophosphane ClPNAr (Ar = 2,4,6‐ t Bu 3 C 6 H 2 ) with the zirconocene [Cp 2 ZrMe 2 ] occurring at −40 °C to give the metalated iminophosphorane 1 can be outlined in this way. Compound 1 reacts with nitriles RCN (R Me, i Pr, Ph) to give the unusual insertion products 2 , and thus behaves as an iminophosphide; at room temperature 1 rearranges to the thermodynamically more stable aminophosphane 3 .
