✦ Synopsis

The in-situ formation at Ϫ30ЊC of the electrophilic phosphinidene complex i Pr 2 NPFe(CO) 4 , resulting from reaction of dichlorophosphine i Pr 2 NPCl 2 with Na 2 Fe(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 Pr 2 NPFe(CO) 4 is less than that of PhPW(CO) 5 , which is, however, generated at much higher temperatures. The stabilization of i Pr 2 NPFe(CO) 4 in the reaction medium is discussed.
