Substituent effects in the iron 2p and carbon 1s edge Near-Edge X-ray Absorption Fine Structure (NEXAFS) spectroscopy of ferrocene compounds

The iron 2p and carbon 1s near-edge X-ray absorption fine structure (NEXAFS) spectra of substituted ferrocene compounds (Fe(Cp-(CH3) 5)2, Fe(Cp)(Cp-COOH), Fe(Cp-COOH)2, and Fe(Cp-COCH3)2) are reported and are interpreted with the aid of extended Hiickel molecular orbital (EHMO) theory and density functional theory (DFT). Significant substituent effects are observed in both the Fe 2p and C 1s NEXAFS spectra. These effects can be related to the electron donating/withdrawing properties of the cyclopentadienyl ligands and their substituents as well as the presence of pi* conjugation between the cyclopentadienyl ligand and unsaturated substituents.

Efficient thiol-yne click chemistry of redox-active ethynylferrocene

The application of ethynylferrocene, FcCCH (1), as a highly efficient electroactive precursor for the thiol-yne click reaction is presented. For this purpose, a wide range of functionalized thiols, namely 2-mercaptoethanol, 1-thioglycerol, 3-mercaptopropionic acid, 4-aminothiophenol, and benzene-1,3-dithiol as well as tetrathiol pentaerythritol tetrakis(3-mercaptopropionate), were investigated. This facile thiol-ethynylferrocene radical reaction has resulted in the quantitative formation and isolation of the newly ferrocenyl-vinyl sulfides FcCH=CHS(CH2)2OH (2Z and 2E), FcCH=CHSCH2CH(OH)CH2OH (3Z and 3E), FcCH=CHS(CH2)2COOH (4Z and 4E), FcC(CH2)S(1,4-C6H4)NH2 (5alpha), FcCH=CHS(1,3-C6H4)SCH=CHFc (6), and [FcCH=CHS(CH2)2COOCH2]4C (7). Thiol-ethynylferrocene reactions have been initiated either by heat, in toluene with AIBN, or by UV light irradiation in THF in the presence of DMPA as photoinitiator. The outcome of the hydrothiolation of ethynylferrocene strongly depends on the thiol structure and on the initiation method employed. A simple mixing of metallocene 1 with the thiol HS(CH2)2OH or HS(CH2)2COOH in a proper ratio, in THF at 20 C, in a initiator-free thiol-yne reaction, causes hydrothiolation of 1 to occur, allowing for the formation of vinyl sulfides 2Z, 2E and 4Z, 4E in good isolated yields. In contrast to the bis-addition typically observed for thiol-yne reactions, no double hydrothiolation to FcCCH has been observed for any of the thiols under any conditions studied. Electrochemical studies showed that tetrametallic compound 7, containing four sulfur-bridged ferrocenyl-vinyl moieties, behaves as a tetrapodal adsorbate molecule, exhibiting excellent chemisorption properties, and spontaneously forms robustly adsorbed 7 films onto Au or Pt electrode surfaces.

The substitution chemistry of the tris(3,5-dimethylpyrazolyl)-methanerhodium complex [Rh(CO)2{HC(pz?)3}]+

The complex [Rh(CO)2{HC(pz?)3}][PF6], 1 +[PF6]- {HC(pz?)3 = tris(3,5-dimethylpyrazolyl)methane}, prepared by reacting [{Rh(CO)2(mu-Cl)}2] with HC(pz?)3 in the presence of Tl[PF6], has a distorted square pyramidal structure with a kappa3-HC(pz?)3 ligand. Carbonyl substitution with Lewis bases gives [Rh(CO)L{HC(pz?)3}] [PF6] {L = PPh3, 2+[PF6]-; L = AsPh3, 3+[PF6]-; L = P(o-tolyl)3, 4+[PF6]-}, which have square planar kappa2 structures, confirmed by X-ray crystallography for 2+[PF6]-. The cations 2+ and 3+ have the third pyrazolyl ring orientated pseudo-parallel to the square planar metal whereas 4+ more likely has the third ring orientated exo to that plane. One-electron oxidation of 2+ and 3+ gives the Rh(II) dications [Rh(CO)(PPh3){HC(pz?)3}]2+, 22+, and [Rh(CO)(AsPh3){HC(pz?)3}]2+, 32+, characterised by ESR spectroscopy. Complex 1+[PF6]- reacts with PhC?CPh to give [Rh(CO)(eta2-PhC?CPh)-{HC(pz?)3}] [PF6], 5+[PF6]-, in which the two-electron donor alkyne occupies an equatorial position in a trigonal bipyramidal kappa3 structure. With MeC?CR (R = Me or Et), 1+[PF6]- gives the kappa2 square planar complexes [Rh{eta4-C4Me2R2C(O)}{HC(pz? )3}][PF6] (R = Me, 6+[PF6]-; R = Et, 7+[PF6]-) in which the cyclopentadienone ligands are coordinated via two Rh-monoalkene bonds; the structurally characterised form of 7+ has the two alkyne units linked head-to-head with the CEt termini bound to the ketonic CO group. With HC?CPh or HC?CH, 1+ gives the octahedral, kappa3 rhodium(III) metallacyclopentadienes [Rh(CO)(eta1:eta1?-CHCRCHCR) {HC(pz?)3}][PF6] (R = Ph, 8+[PF6]-; R = H, 9+[PF6]-) with the two alkynes linked head-to-tail in 8+. The reaction of 1+ with HC?CH also gives the cycloheptatrienone (tropone) derivative [Rh{eta4-C6H6C(O)}{HC(pz?)3} ][PF6], 10+[PF6]-, with a kappa3 ligand and the cycloheptatrienone ligand bound to the metal via two Rh-C sigma-bonds and one Rh-monoalkene interaction.

Reactions of Cp2TiMe2 with ferrocene and (n5-Cp)Co(n4-C4Ph4) derived esters and amides: A new route for 1-methylvinyl and methyl ketone derived metal sandwich compounds

Reactions of Cp2TiMe2, with the ester derivatives of organometallic sandwich compounds (n5-RC5H4)Fe(n5-C5H5) and (n5-RC5H4)Co(n4-C4Ph4) (R=ester groups) gave products having R=C(CH2)Me, instead of the expected vinyl ethers indicating conversion of the ester units by Cp2TiMe2 to methyl ketones followed by methylenation. A reaction of Cp2TiMe2 with the diester (n5-RC5H4)Co(n4-C4Ph3R)(R=C(O)OMe) also gave similar results. The study has also been successfully extended to metal sandwich derived amides, thio and seleno esters. By controlling the amount of Cp2TiMe2, the reactions were also stopped at the methyl ketone stage and the methyl ketones were isolated in good yields and characterized. The method provides an easy and direct access to convert organometallic sandwich derived esters and related compounds to 1-methylvinyl derived products.
