Abstract

The in-situ formation at -30°C of the electrophilic phosphinidene complex (i)Pr₂NPFe(CO)₄, resulting from reaction of dichlorophosphine (i)Pr₂NPCl₂ with Na₂Fe(CO)₄ (Collman's reagent), was demonstrated by trapping reactions with various alkynes. The resulting phosphirenes were obtained in good yields. The reactivity of (i)Pr₂NPFe(CO)₄ is less than that of PhPW(CO)₅, which is, however, generated at much higher temperatures. The stabilization of (i)Pr₂NPFe(CO)₄ in the reaction medium is discussed.
