Abstract
The phosphinidene complex iPr2N–P═Fe(CO)4 was prepared as a storable phosphirane solution from Collman’s reagent and iPr2NPCl2 in the olefins 1-pentene and 1-hexene. The carbene-like reagent is able to hop under very mild conditions (>−25 °C) from one olefin to another and to alkynes to give the more stable phosphirenes that
