Novel synthesis of pi-conjugated molecules by cross-metathesis reaction of vinylferrocene with a series of vinylarenes was investigated with a molybdenum-based Schrock catalyst (CHCMe2Ph)Mo(N-2,6-i-Pr2C6H3)[OCMe(C F3)2]2. The cross-metathesis reactions occurred successfully and the cross-metathesis product, i.e., heterodimers, were readily obtained selectively, together with only small amounts of the corresponding self-dimers.

A series of meso-ferrocenyl-porphyrin dyads linked by four different pi-conjugated bridging units (directly bound, vinyl, ethynyl, and phenyl) have been synthesized to investigate the influence of the conjugated linker on both the electronic and photochemical properties of the porphyrin chromophore. The basic structure consists of 5-(Fc)-15-(4-methylbenzoate)-10,20-diphenylporphyrin zinc(II), where Fc = ferrocene, vinylferrocene, ethynylferrocene, or phenylferrocene. Upon introduction of the various electron-donating ferrocenyl moieties at the meso-position of the porphyrin ring, Soret and Q-band electronic transitions of the resultant dyads are red-shifted compared with those of the nonferrocenyl reference porphyrin system 15-(4-methylbenzoate)-10,20-diphenylporphyrin zinc(II). The electronic properties of these systems have been investigated by electrochemical (cyclic voltammetry) and computational (DFT/TDDFT) methods, while UV/vis absorption and fluorescence emission spectroscopic analysis is also presented. Collectively, electronic and photophysical analysis indicate a strong electronic communication between the porphyrin macrocycle and directly bound ferrocenyl, vinylferrocenyl, and ethynylferrocenyl dyads. The presence of a phenyl spacer acts to inhibit such electronic communication due to the orthogonal geometry of the bridging phenyl ring at the meso-position of the porphyrin macrocycle. In addition to electronic factors, and in particular for the directly bound 5-(ferrocenyl)-15-(4-methylbenzoate)-10,20-diphenylporphyrin zinc(II) dyad, computational analysis suggests that a significant ruffling of the porphyrin macrocyle from planarity is required to facilitate the bulky ferrocene group directly at the meso-position. Of particular note for each of the meso-ferrocenyl-porphyrin dyads is how fluorescence emission derived from the porphyrin S1 (pi-pi) excited state is quantitatively quenched due to photoinduced charge-transfer from the ferrocene unit onto the excited state porphyrin. Spectroelectrochemical studies demonstrate redox off/on switching of the porphyrin fluorescence emission via ferricenium/ferrocene redox cycling. Interestingly, it was found that the S0 ? S1 fluorescence emission is also switched-on following titration with the metal ions Ce(IV), Cu(II), and Fe(III) in acetonitrile.

The emergence of resistance against existing antileishmanial drugs necessitates the search for new classes of antileishmanial compounds. Herein a series of structurally diverse ferrocenylquinolines have been synthesized and evaluated for in?vitro antileishmanial activity against Leishmania donovani using?the MTT assay. Thirteen (M2-M14) substituted ferrocenylquinoline congeners possessing triazole?rings?were generated by palladium mediated Suzuki-Miyaura coupling reaction of 5-iodoferrocenylquinolinetriazole and substituted arylboronic acids. All the synthesized compounds were tested for its antileishmanial activity using both promastigote and amastigote stages of L.?donovani. Among them, three compounds (M4, M7 and M9) exhibited promising anti-promastigote activity, with an IC50value of 28.7?muM, 22.1?muM and 28?muM, respectively, and no cytotoxicity toward host splenocytes. These three compounds are equally effective against the intracellular amastigote stage of L.?donovani showing the IC50values of 16?muM (M4), 8?muM (M7) and 16?muM (M9), respectively, with consistent nitric oxide generation as required for parasite clearance. From the battery of tests conducted in this study, it appears that these compounds induce parasite death by promoting cell cycle arrest and triggering apoptosis.

o-Carboryne (1,2-dehydro-o-carborane) is a very useful synthon for the synthesis of a variety of carborane-functionalized molecules. Using 1-Li-2-OTf-o-C2B10H10 as a precursor, o-carboryne undergoes an efficient [2 + 2] cycloaddition with a large variety of vinyl ethers at room temperature to give a series of carborane-fused cyclobutanes in very good to high isolated yields. This reaction is compatible with many functional groups and has a very broad substrate scope ranging from alkyl- to aryl- and to silyl-substituted vinyl ethers. A stepwise reaction mechanism is proposed based on the control experiments, which is supported by DFT calculations. All new compounds have been fully characterized by 1H, 13C, and 11B NMR spectroscopy as well as HRMS spectrometry. Some are further confirmed by single-crystal X-ray analyses.

The catalytic asymmetric construction of silicon-stereogenic silanes is of great interest and significance, but has met with only limited success to date. We herein report the enantioselective hydrosilylation of alkenes with dihydrosilanes by a chiral half-sandwich scandium catalyst, which constitutes an efficient and general route for the synthesis of a wide range of enantioenriched silicon-stereogenic silanes from easily accessible starting materials. This reaction features a broad substrate scope, high yields, and high enantioselectivity. Some of the chiral tertiary silane products were also converted into valuable derivatives, such as chiral silanol, quaternary silane, and benzosilole compounds.

X-ray absorption spectroscopy (XAS) was used to study the electrochemical incorporation of perrhenate anion, from a 0.1 M NH4ReO4 solution, into poly(vinylferrocene) (PVFc) and a modified PVFc (a copolymer of 30% t-butyl acetylferrocene and 70% t-butyl divinyl ferrocene). The polymers were deposited on a carbon cloth current collector from a solution of the polymers in CH2Cl2. In situ XAS measurements were done at the Fe K edge on the reduced polymers and at 0.9 V vs. Ag/AgCl. Ex situ XAS was done at the Re L3 edge after oxidation of the polymers at 0.9 V. The oxidized electrodes were washed in water to remove dissolved NH4ReO4 in the electrode pores. XAS was done both on wet-washed electrodes and on electrodes that were dried. XAS showed that at 0.9 V the Fe was oxidized from a ferrocene to a ferrocenium moiety and the Fe-C bond distance increased from 2.05 to 2.08 A. Both the X-ray absorption near-edge spectroscopy and extended X-ray absorption fine structure (EXAFS) results are consistent with having >75% of the ferrocene moieties in the polymer oxidized at 0.9 V. The Fe K-edge EXAFS showed no direct indication of interaction of Fe with ReO4-. At the Re L3 edge the only indication of interaction of ReO4- with the polymers was a slight change in the XANES features.
