abstract = {By reacting [{Cp‴Fe(CO)2}2(µ,η1:1-P4)] (1) with in situ
generated phosphenium ions [Ph2P][A] ([A]− = [OTf]− =
[O3SCF3]−, [PF6]−), a mixture of two main products of
the composition [{Cp‴Fe(CO)2}2(µ,η1:1-P5(C6H5)2)][PF6]
(2a and 3a) could be identified by extensive 31P NMR
spectroscopic studies at 193 K. Compound 3a was also
characterized by X-ray diffraction analysis, showing the
rarely observed bicyclo[2.1.0]pentaphosphapentane unit. At
room temperature, the novel compound
[{Cp‴Fe}(µ,η4:1-P5Ph2){Cp‴(CO)2Fe}][PF6] (4) is formed
by decarbonylation. Reacting 1 with in situ generated
diphenyl arsenium ions gives short-lived intermediates at
193 K which disproportionate at room temperature into
tetraphenyldiarsine and
[{Cp‴Fe(CO)2}4(µ4,η1:1:1:1-P8)][OTf]2 (5) containing a
tetracyclo[3.3.0.02,7.03,6]octaphosphaoctane ligand.},
