Benzene-, iron

The known reactions involving transfer of a C5HSBR ligand are collected in Table VII. Alternative syntheses are available for the bis(borata-benzene)iron complexes 65 and 18 only (55). In the system 7/Ni(CO)4 the main product is Co(CO)2(C5H5BMe) (15), and 66 is obtained as a thermally unstable by-product (47). In solution, 66 adopts a folded, doubly CO-bridged structure with a dihedral angle of 121° for the Ni2(CO)2 moiety (47).

Iron complexes with organic ligands are widely used as such reservoirs. For example, the stable 19-electron complex cyclopentadienyl benzene iron(I) is a clean electron reservoir that has a sufficiently negative oxidation potential and can be easily made, stored, and handled and can be weighed accurately (Alonso Astruc 2000).

Cationic polymerization of thiiranes CMT (9-(thiiran-2-ylmethyl)-9//-carbazole) 217 and PMT (10-(thiiran-2ylmethyl)-1077-phenothiazine) 218 was studied by a Lithuanian group <2002JPH63>. Initiators were di-(/-butylphenyl)iodonium tetrafluoroborate (BPIT), diphenyliodonium tetrafluoroborate, cyclopropyldiphenylsulfonium tetrafluoroborate, and ( 7 -2,4-cyclopentadien-1 -yl) [1,2,3,4,5,6- )-( 1 -methylethyl)benzene]-iron(- -)-hexafluorophosphate(—1). The influences of temperature and initiator concentration on the polymerization rate and the conversion limit were determined. The values of initiator exponent and activation energy for the photopolymerization of CMT and PMT initiated with BPIT in 1,2-dichloroethane was established. 

The Dewar-benzene iron carbonyl derivative [97], like perfluorobicyclo[2,2,0]hexa-2,5-diene itself, undergoes Diels-Alder addition to give [98a and b], with the chemical shifts shown. (53) [98a] is also formed, although in low yield, by the reaction of the preformed Diels-Alder adduct [99] with Na[(7r-C5H5)Fe(CO)2], confirming the stereochemistry of the addition. 

The treatment of ferrocene with aluminum powder, aluminum chloride, and benzene results in the exchange of benzene for the cyclopentadienyl ligand to give a [cyclopentadienyl benzene iron]" cation. Further ligand exchange is very difficult. 

Not all bis-7t-arene cations disproportionate affording neutral jr-arene sandwich complexes. Thus the bis-Ji-benzene iron cation readily undergoes hydrolytic decomposition [30], whilst reduction of the bis-jr-arene cations...
