A new family of heterometallic compounds 3-6 containing ferrocenyl and platinum(ii) centers has been synthesized by reaction of 1-beta- aminoethylferrocene (1) and 1,1?-bis(beta-aminoethyl)ferrocene (2) with Pt(ii) precursors. Using K2[PtCl4] as the Pt(ii) source, the cis-square-planar neutral compounds [Fe{eta5-C 5H4(CH2)2NH2} 2PtCl2] (3) and [{Fe(eta5-C5H 4(CH2)2NH2)(eta5-C 5H5)}2PtCl2] (5) were obtained. Reaction of cis-[PtCl2(dmso)2] with 1 and 2 resulted in the displacement of dmso and chloride ligands from the platinum coordination sphere, affording the cationic and neutral compounds [Fe{eta5- C5H4(CH2)2NH2} 2Pt(dmso)Cl]Cl (4) and [Fe(eta5-C5H 4(CH2)2NH2)(eta5-C 5H5)Pt(dmso)Cl2] (6). Compounds 3-6 were thoroughly characterized using multinuclear (1H, 13C, 195Pt) NMR, IR spectroscopy, ESI mass spectrometry and elemental analysis. Single-crystal X-ray analysis of heterometallic 6 confirmed the cis geometry of the molecule and revealed that the platinum atom is held in a perfect square-planar geometry. The electrochemical behaviour of the heterometallic compounds 3-6, which has been examined by cyclic (CV) and square wave (SWV) voltammetries in dichloromethane and dmso solution, is characterized by the reversible one-electron oxidation of the ferrocene moieties. The results of the biological activity studies revealed that the organometallic complex 5 is active against all cell lines with GI50 values in the range 1.7-2.3 muM. When compared to the standard anticancer drug cisplatin, heterotrimetallic 5, possessing two aminoethylferrocenyl units coordinated to the Pt(ii) center, showed a greater activity profile in the colon cancer cell line. Cell cycle studies revealed that the new mixed compound exhibits a mechanism of action different to cisplatin.

1,1?-Bis(pyrazol-3-yl)ferrocene: A Clip Ligand That Forms Supramolecular Aggregates and Prismatic Hexanuclear Coinage Metal Complexes

Two ferrocene derivatives with appended pyrazole substituents, namely, 1,1?-bis(5-methyl-1H-pyrazol-3-yl)ferrocene (H2LH) and 1,1?-bis(5-trifluoromethyl-1H-pyrazol-3-yl)ferrocene (H2LF), were synthesized. In solid state they form distinct H-bonded dimers with orthogonal (H2LH, C2 symmetry) or antiparallel (H2LF, C2h symmetry) arrangement of the two ferrocene/pyrazole hybrid molecules. Supramolecular dimerization was also detected in solution at low temperatures, though diffusion-ordered spectroscopy and variable-temperature NMR spectroscopy revealed several dynamic processes. Redox potentials of the ferrocene derivatives are affected by the nature of the pyrazole substituent (Me, CF3). In their deprotonated form [LR]2-, both ferrocene/pyrazole hybrids serve as ligands and form oligonuclear CuI, AgI, and AuI complexes that were identified by matrix-assisted laser desorption ionization mass spectrometry. X-ray crystallography revealed the structures of Cu6L3H and Ag6L3F, which both contain two parallel and eclipsed [M(mu-pz)]3 metallamacrocycles (M = Cu, Ag) linked by three ferrocene units. MI…MI distances between the two triangular M3N6 decks are shorter in Ag6L3F (3.28-3.30 vs 3.44-3.51 A in the case of Cu6L3H), indicating substantial intramolecular closed-shell Ag(d10)-Ag(d10) interactions. However, Cu6L3H features close intermolecular Cu…Cu contacts as short as 3.37 A. Moessbauer data for both the ligands and complexes were collected, and electrochemical properties were measured; preliminary luminescence data are reported. (Figure Presented).

Alkoxymethylation of ferrocenylalkenes

The reaction of ferrocenylalkenes with chloromethyl alkyl ethers catalyzed by Lewis acids gives 3-alkoxy-1-ferrocenyl carbocations, which can be trapped by nucleophiles to give 1,3-disubstituted ferrocenylalkane derivatives.The application of this reaction to the preparation of chiral 3-hydroxy-1-ferrocenylalkylamines is described; their structures and conformations have been elucidated by NMR spectroscopy.The stereochemical course of the alkoxymethylation reaction involves “exo” attack of the chloromethyl ether at the beta carbon of the double bond relative to the ferrocene, and subsequent “exo” attack of the nucleophile at the carbocationic centre formed in the first step.

Phthalocyanines prepared from 4-chloro-/4-hexylthio-5-(4-phenyloxyacetic acid)phthalonitriles and functionalization of the related phthalocyanines with hydroxymethylferrocene

The phthalonitrile derivative chosen for the synthesis of substituted phthalocyanines [M: 2H, Zn(II), Co(II)] with four chloro and four phenyloxyacetic acid substituents on the periphery is 4-chloro-5-(4-phenyloxyacetic acid)phthalonitrile. The sodium salt of carboxyl substituted zinc phthalocyanine is good soluble in water. Further reactions of zinc and cobalt phthalocyanines bearing phenyloxyacetic acid with thionylchloride gave the corresponding acylchlorides. This functional group reacted with hydroxymethylferrocene in dry DMF to obtain ferrocenyl substituted phthalocyanines. Also chloro substituent in new phthalonitrile was substituted with hexylsulfanyl substituent and its cyclotetramerization in the presence of Zn(AcO)2·2H2O and 2-(dimethylamino)ethanol resulted with zinc phthalocyanine. The compounds have been characterized by elemental analysis, MALDI-TOF mass, FT-IR, 1H NMR, UV-Vis and fluorescence data. Aggregations properties of phthalocyanines were investigated at different concentrations in tetrahydrofuran, dimethylformamide, dimethylsulfoxide, water, and water/ethanol mixture. Also fluorescence spectral properties are reported.

Homochiral arsenic-/phosphorus-based ligands

The synthesis of homochiral phosphorus-based ligands has escalated dramatically over the last decade in the drive to develop new, and further fine tune existing, base structures of chiral auxiliaries that have had, and most certainly are continuing to have, a phenomenal impact in the arena of enantioselective catalysis. This review highlights the vast array of homochiral phosphorus-based ligands and their significantly fewer arsenic-based analogs, the key synthetic strategies used to prepare them and the significant roles that they have been employed in after coordination to a transition metal center.

Catalytic Oxo/Imido Heterometathesis by a Well-Defined Silica-Supported Titanium Imido Complex

Grafting Ti(=NtBu)(Me2Pyr)2(py)2 (Me2Pyr= 2,5-dimethylpyrrolyl, py=pyridine) onto the surface of silica partially dehydroxylated at 700 C gives the well-defined silica-supported Ti imido complex (?SiO)Ti(=NtBu)(Me2Pyr)(py)2, which is fully characterized by IR and solid-state NMR spectroscopy as well as elemental and mass balance analyses. While stoichiometric imido-transfer reactivity is typical for Ti imides, the obtained surface complex is unique in that it enables catalytic transformations involving Ti imido and oxo intermediates. In particular, it efficiently catalyzes imidation of carbonyl compounds with N-sulfinylamines by oxo/imido heterometathesis.
