Ferrocenophane, in which the two ferrocene rings are linked by ester bonds and p-substituted benzene rings, has been synthesized by the reaction of hydroquinone with 1,1′-bis(chloroformyl)ferrocene. The structure of the compound has been studied on the basis of the NMR and electronic spectra.

Abstract Ferrocenylruthenocene reacts with sulfuric acid–NH4BF4 to give a mono-oxidized diamagnetic ferrocenylruthenocenium BF4− salt, while it reacts with p-benzoquinon–BF3(Et2O) to give a trioxidized paramagnetic ferrocenylruthenocenium (BF4−)3 salt. Mössbauer parameters of the former salt are very similar to those of neutral ferrocenylruthenocene, suggesting that the structure of the salt is expressed as [Cp(C5H4)Fe(II)(C5H4)CpRu(III)–Ru(III)Cp(C5H4)Fe(II)(C5H4)Cp]2+(BF4−)2 with an antiferromagnetic ...

[Chemical reaction: see text] New chiral pyridine derivatives possessing the planar chirality of the ferrocene have been prepared by means of an aldolization-crotonization reaction. This very simple reaction has been applied to the synthesis of isomers 1-4 that differ in the position of the nitrogen atom on the pyridine ring. Following the same procedure, asymmetric synthesis of 1 has been achieved using an enantiopure ferrocenylzinc intermediate. This method has also allowed the preparation of ...

SYNTHESIS OF BIOACTIVE HETEROCYCLIC FERROCENE DERIVATIVES.The discovery of ferrocene marked one of the points of departure for modern organometallic chemistry.In general, the compounds of ferrocene derivatives are widely applied in several areas.One of the most important applications of ferrocene is the development of more active drugs, especially in cases where there is resistance to current drugs.Bioactive agents containing ferrocene have proven effective in combating diseases such as cancer, ...
