Insertion of the PC-functionality of (pentamethylcyclopentadienyl)(dicarbonyl)[1,3,3-tris(trimethylsilyl)–η1-1,2-diphosphaallyl]iron into a C5Me5 C–H bond: formation of a chelating (η1-P, η5-C5)-3-tetramethylcyclopentadienyl-1,2-diphosphapropanido Ligand

Abstract

Heating a methylcyclohexane solution of [(η⁵-C₅Me₅)(CO)₂Fe–P(SiMe₃)–PC(SiMe₃)₂]1 gives rise to the insertion of the PC-moiety into the CH-bond of a ring methyl group forming the chelate complex {η⁵-C₅Me₄CH₂P[CH(SiMe₃)₂]P(SiMe₃)Fe(CO)₂}5 which is trapped by (Z-cyclooctene)Cr(CO)₅ and fully characterized as its Cr(CO)₅ adduct 6.
