Addition of isonitriles to [(OC) 3 Fe(μ‐CO)(μ‐Ph 2 PNHPPh 2 )Pt(PPh 3 )] 1 produces the μ‐isonitrile complexes [(OC) 3 Fe(μ‐C=NR)(μ‐Ph 2 PNHPPh 2 )Pt(PPh 3 )] 2 , which are transformed to the μ‐aminocarbyne complexes [(OC) 3 Fe{μ‐CN(El)R}(μ‐Ph 2 PNHPPh 2 )Pt(PPh 3 )] + ; 3 and 4 by electrophilic addition of [El][BF 4 ] or [El][OSO 2 CF 3 ] (El = H, Me). The dppa backbone of 4 is readily deprotonated by KOSiMe 3 to yield the very stable zwitterionic aminocarbyne complex [(OC) 3 Fe{μ‐CN(Me)2,6‐xylyl}(μ‐Ph 2 PNPPh 2 )Pt(PPh 3 )] 5 .
