Stereoselective synthesis of ferrocene-based C2-symmetric diphosphine ligands: Application to the highly enantioselective hydrogenation of alpha-substituted cinnamic acids

(Chemical Equation Presented) Chirality3: A new ferrocene-based diphosphine ligand is applied to the asymmetric hydrogenation of alpha-substituted cinnamic acids. The P-centered-, C-centered-, and planar-chiral ligand (RC,RC,SFc,S Fc,SP,SP)-1 displays unprecedented enantioselectivity in this Rh-catalyzed reaction (see scheme; cod = cycloocta-1,5-diene).

Ferrocenyl anthracenes: Synthesis and molecular structure

The synthesis of a series of ferrocenylanthracene derivatives is described, utilising the palladium catalysed coupling reaction of 1,1?-bis(chlorozincio)ferrocene with halo-anthracenes. Bis-1,1?-(9-anthracenyl)ferrocene (1) was characterised by single crystal X-ray diffraction and shows an eclipsed ferrocenyl geometry. X-ray crystallographic studies indicate that there are no clear stacking interactions of either an intra-or intermolecular nature between the anthracenyl rings in the structure. A series of 9-and 10-disubstituted ferrocenylanthracene derivatives has also been prepared. In each case the palladium catalyst (Pd(dppf)Cl2) is recovered in a modified form, e.g. as the [(dppf)PdBr(9-anthracenyl)] complex in the synthesis of bis-1,1?-(9-anthracenyl)ferrocene. The single crystal X-ray structure of one such palladium complex [(dppf)PdBr-{9-(10-chloroanthracenyl)}] (15a) has been determined in a case where chloride/bromide exchange had occurred in the palladium complex intermediate. The potential application of compound 1 as synthon for the construction of a molecular sensing device is discussed. Cyclic voltammetry and fluorescence studies have been carried out for selected derivatives.

The design and synthesis of a new potentially C3-symmetric ferrocenylphosphine

A new potentially C3-symmetric phosphine ligand ‘manphos’ has been obtained and fully characterized. The ligand which is a tri-ferrocenyl-tetra-phosphine is obtained in a simple and effective two step synthesis starting from 1,1?-dibromoferrocene via the intermediate compound tris-(1?-bromoferrocenyl)phosphine or alternatively via 1′-bromo-1-diphenylphosphinoferrocene. The iso -propylphosphino-analogue of manphos, tris-(1′-diisopropylphosphinoferrocenenyl)phosphine, has also been obtained, in addition to several functionalised derivatives of triferrocenylphosphine where the ferrocene rings have been substituted in the 1?-position.

Substituent effects on ferrocenes in aluminum chloride-butylpyridinium chloride molten-salt mixtures

The visible absorption spectra and reduction potentials of 11 ferrocenes containing electron-withdrawing substituents were determined in an N-n-butylpyridinium chloride-aluminum chloride molten salt. When the substituent(s) on the cyclopentadienyl ring(s) of ferrocene were varied, the reduction potential was caused to range over 1.25 V, and the wavelength for maximum absorption of visible light was varied by nearly 200 nm. These changes are greater than have been observed for similar ferrocenes in other nonaqueous solvents. Evidence is presented for specific interactions of particular ferrocenes with the molten salt.

The synthesis and metal coordination chemistry of a novel phosphine- and thiolate-substituted ferrocenediyl ligand

The synthesis and metal coordination chemistry of a phosphine- and thiolate-substituted ferrocenediyl ligand were discussed. Bridged dimeric species, with the thiolate S adopting a binucleating role were found to be observed for Pd(II) and Rh(I) metal centers while a mononuclear, square planar Ni(II) complex was formed on reaction of the ligand with [Ni-(TMEDA)Me2]. It was found that the rhodium complexes with phosphorus-sulfur donor ligands showed excellent activities and stability as methanol carbonylation catalysts.

An efficient catalytic synthesis and characterization of new styryl-ferrocenes and their trans-pi-conjugated organosilicon materials

A selective and efficient catalytic method was developed for the synthesis of new styryl-conjugated silyl-ferrocene materials. The use of an effective palladium catalytic system [Pd(eta2-dba)(P(o-tolyl)3)2] (3) with a K3PO4 base solution allowed us to obtain new, reactive ferrocene olefins which can be used in various applications. In addition, using the stereo-control silylative coupling reaction we received unique new organosilicon trans-vinylene products with a built-in metallocene.

The conversion of 1,1?-dibromoferrocene to 1,2-dibromoferrocene: The ferrocene-chemist’s dream reaction

The conversion of 1,1?-dibromoferrocene to a range of 2-substituted bromoferrocenes is described. The products are useful in the preparation of a wide number of 1,2-disubstituted ferrocenes. This includes the preparation of 1,2-dibromoferrocene and 2-(diisopropylphosphino)bromoferrocene in what is a clean and simple synthesis. The synthesis may be carried out on a large scale and for the first time produces multigram quantities of these important precursor compounds. In addition the synthetic procedure may be modified to produce a new family of ferrocene-based tris-phosphine ligands such as bis(2-diphenylphosphinoferrocenyl)phenylphosphine.
