Application of 246047-72-3, An article , which mentions 246047-72-3, molecular formula is C46H65Cl2N2PRu. The compound – (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium played an important role in people’s production and life.

A diverse array of multiwalled carbon nanotube (MWCNT) sensory materials have been synthesized and used to create sensors capable of identifying volatile organic compounds (VOCs) on the basis of their functional groups. Functionalized MWCNTs with a series of cross-sensitive recognition groups were successfully synthesized via zwitterionic and post-transformation synthetic procedures. The incorporated chemical functional groups on MWCNT surfaces introduced greatly increased sensitivity and selectivity to the targeted analytes. The distinct response pattern of each chemical was subjected to statistical treatments, which led to a clear separation and accurate identification of 100% of the VOCs. These results demonstrate that covalent functionalized MWCNT-based sensor arrays are a promising approach for low-cost, real time detection and identification of VOCs.

A process of preparing an unsaturated alcohol (olefin alcohol), such as, a homo-allylic mono-alcohol or homo-allylic polyol, involving protecting a hydroxy-substituted unsaturated fatty acid or fatty acid ester, such as methyl ricinoleate, derived from a seed oil, to form a hydroxy-protected unsaturated fatty acid or fatty acid ester; homo-metathesizing or cross-metathesizing the hydroxy-protected unsaturated fatty acid or fatty acid ester to produce a product mixture containing a hydroxy-protected unsaturated metathesis product; and deprotecting the hydroxy-protected unsaturated metathesis product under conditions sufficient to prepare the unsaturated alcohol. Preferably, methyl ricinoleate is converted by cross-metathesis or homo-metathesis into the homo-allylic mono-alcohol 1-decene-4-ol or the homo-allylic polyol 9-octadecene-7,12-diol, respectively.

A library of 32 organoruthenium compounds has been synthesised. Known and novel C-N cyclometalated compounds as well as N-C-N and N-N-C pincer derivatives of this metal have been used in this purpose. Most of the compounds have been tested for their in vitro antitumoral behaviours, good to excellent activities have thus been found. Several of the newly synthesized compounds pass the symbolic barrier of the nanomolar range for their IC50 indicating a critical improvement. The level of activity is tentatively correlated to physicochemical properties of the compounds such as their RuIII/II redox potential and their lipophilicity (logP).

The present invention relates to relates to macrocyclic small molecule inhibitors of the Sonic Hedgehog signaling pathway, syntheses thereof, and intermediates thereto. Such small molecule modulators of the Sonic Hedgehog signaling pathway are useful in the treatment of proliferative diseases (e.g., basal cell carcinoma, Gorlin syndrome, medulloblastoma, or pancreatic cancer), pulmonary diseases (e.g., interstitial pnuemonitis or interstitial pulmonary fibrosis), and developmental disorders (e.g., phocomelia or cyclopia). Novel non-natural macrocycles are provided that inhibit Sonic Hedgehog induced-protein transcription.

The Cp(PPh3)2Ru-nCR=CH2 complexes 2 – 4 (n = 0, 2, R = H; n = 3, R = CH3) are prepared by treatment of the chloride 1 with the appropriate organomagnesium halides.The vinyl complex 2 eliminates a PPh3 ligand above 100 deg C and reacts with ethylene (20 – 30 bar) by insertion into the Ru – vinyl bond to give the (eta3-1-methylallyl)ruthenium complex 6a.The 3- and 4-alkenyl compounds 3 and 4 isomerize at 80 – 100 deg C after dissociation of one PPh3 via an (eta2-alkadiene)hydridoruthenium intermediate, e.g. 7, to form the eta3-allyl complexes 6, 8, and 9, respectively.The stable (eta1,eta2-4-alkenyl)ruthenium compounds 10 – 12 are formed if isomerization by beta-H-elimination is prevented by E-configuration of Ru and beta-H in a conformatively inflexible cyclopropyl system.The 31P chemical shifts of 2 – 4 and the (eta1-allyl)ruthenium complexes, of 10 – 12, and of the eta3-allyl complexes 6a, 8, 9, 13a are characteristic for the corresponding type of compounds.

Photoinduced intramolecular electron transfers within ligand-bridged Ru(II) and Co(III) compounds of <(bpy)2Ru(L)Co(bpy)2>(5+) (a, b, and c) were examined in butyronitrile by means of laser photolysis kinetic spectroscopy, where L is a bridging tetradentate ligand, 2,6-bis(2-pyridyl)benzodiimidazole for a, 2,2′-bis(2-pyridyl)bibenzimidazole for b, and 1,5-bis<2-(2-pyridyl)benzimidazoyl>pentane for c.The temperature dependence of the rates of electron transfer and intersystem crossing is analyzed by taking the temperature dependence of the Gibbs energy change and reorganization energy into account.A transient difference absorption band at 420 nm observed after the picosecond laser excitation of a and b is not ascribed to the formation of excited Ru(II) moiety but to the reaction product (2Co(II)) of the Co(III) moiety, which decayed to form a long-lived species of 4Co(II) within 1 ns below 270 K.The inner-sphere reorganization of the intersystem crossing of 2Co(II) -> 4Co(II) is estimated to be 0.6 eV from the temperature dependence of the transition rate.The electron transfer from the excited MLCT state of the Ru(II) moiety to Co(III) for c occured within 1 ns at 300 K.The inner-sphere reorganization energy (0.6 eV) of the electron transfer was determined from the temperature-dependent electron transfer rate observed.The back electron transfer from 4Co(II) to 2Ru(III) was much slower than the initial electron transfer.It is not the small electronic coupling between 4Co(II) and 2Ru(III) but the negative entropy change (-1.3 meV/K) of Co(II) oxidation that is responsible for the small frequency factor of the electron transfer process.The inner-sphere organization energy of the back electron transfer was determined (1.1-1.3 eV) from the temperature-dependent rate.

The molecular building blocks Fe(II)Pc (Pc = phthalocyaninato2-), Fe(III)Pc, ZnPc, Cp(dppe)Fe, and Cp(PPh3)2Ru were combined in the cyanide-bridged dinuclear reference compounds with M-CN-ZnPc and M-CN-FePc-CN arrays containing Fe(II)Pc and Fe(III)Pc. The linear trinuclear species with the M(mu-CN)Fe(mu-CN)M’ backbone were prepared for both Fe(II)Pc and Fe(III)Pc centers, for terminal Fe/Fe, Fe/Ru, and Ru/Ru combinations and for all three possible cyanide orientations (M-CN-Fe-NC-M’, M-CN-Fe-CN-M’, and M-NC-Fe-CN-M’). The 15 complexes obtained were identified from their IR spectra and six structure determinations. The preferred orientation of the cyanide bridges could be established starting from the [Fe-NC-Fe(III)Pc-CN-Fe]+ complex, which is labile in solution and isomerizes to the corresponding [Fe-CN-Fe(III)Pc-NC-Fe]+ complex. A kinetic analysis of this isomerization has yielded an activation barrier of roughly 110 kJ/mol.

A new series of mono and binuclear Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II), La(III), Ru(III), Hf(IV), ZrO(II) and UO2(II) complexes of phenylaminodibenzoylhydrazone have been synthesized and characterized by elementals analyses, IR UV-vis spectra, magnetic moments, conductances, thermal analyses (DTA and TGA) and electron spin resonance (ESR) measurements. The IR spectral data show that, the ligand behaves as a neutral bidentate type (15 and 16), monobasic bidentate type (6), or monobasic tridentate type (5, 7, 8, 10, 11, 13, 14, 17-21) or dibasic tridentate type 2-4, 9 and 12 towards the metal ion. Molar conductances in DMF solution indicate that, the complexes are non-electrolytes. The ESR spectra of solid complexes (9 and 10) show axial and non-axial types indicating a d(x2 – y2) ground state with significant covalent bond character. However, complexes (11 and 12), show isotropic type, indicating manganese(II) octahedral geometry. Antibacterial and antifungal tests of the ligand and its metal complexes are also carried out and it has been observed that the complexes are more potent bactericides and fungicides than the ligand.
