Graphical Abstract
Remarkable parallels to Hittorf's phosphorus are exhibited by the P11 ligand (unknown in the free form) of the trinuclear iron complex (see structure), which forms as a by-product in the thermolysis of the title compound (CpR=iPr5C5) in the presence of PhC≡CPh. However, the main product of the reaction is, as in the case of CpR=C5H2tBu3, the sandwich complex [CpRFe(η5-P3C2Ph2)] with a 1,2,3-triphospholyl ligand.
