The syntheses and characterization of a series of chromium(III) complexes of the general types trans-[(A)4Cr(OH)-(H2O)]2+, trans-[(A)4Cr(OH)2]+, and trans-[(A)4Cr(H2O)2]3+ are described. The ligands (A)4 used include the tetradentate ligand 1,4,8,11-tetraazacyclotetradecane (cyclam), its hexamethylated derivative C-meso-5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane (cyca), and the bidentate ligand 2-aminomethylpyridine (pico). The cobalt(III) aquahydroxo complexes with cyclam and cyca are also reported. The trans-diaqua and trans-dihydroxo complexes are monomeric, but the trans-aquahydroxo complexes form linear chains. The complexes trans-[Cr(cyclam)(OH)(H2O)](CF3SO3)2 1 and trans- [Co(cyclam)(OH)(H2O)](CF3SO3)2 3 and their corresponding perchlorates (2 and 4, respectively) have been isolated and the structures of the chromium triflate salt 1 and the cobalt perchlorate salt 4 have been determined. Both of these complexes 1 and 4 form infinite chains in the solid state, adjacent metal centers being bridged by hydrogen bonds between hydroxo and aqua ligands. The Cr … Cr separation in 1 is 6.085 A whereas the Co … Co separation in 4 is 6.078 A. The complex trans-[(pico)2Cr(OH2)2](NO3)3 ·H2O 8 (where pico is picolylamine, 2-aminomethylpyridine) crystallizes with only one monomeric formula in a unit cell. In contrast to the structures of 1 and 4 (and, presumably, of 2 and 3 also), the two complexes trans-[Cr(cyclam)(OH)2]-ClO4·H2O 5 and 8 are monomeric in the solid state. The chromium complex trans-[Cr(cyca)(OH)(H2O)](ClO4)2·H2 O 6 crystallizes with two monomeric formula units in a unit cell and the cobalt analogue 7 is isomorphous with the chromium complex. The structures of these complexes are also linear chains, but in this case there is an intervening water molecule between the aqua and hydroxo ligands on adjacent chromium centers. EPR spectroscopy of the chromium complex 1 doped in the diamagnetic cobalt host 3 reveals the presence of weak magnetic interactions.

Synthetic Route of 56100-22-2, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.56100-22-2, Name is 6-Methyl-2,2′-bipyridine, molecular formula is C11H10N2. In a article，once mentioned of 56100-22-2

Upon complexation with Pd(II) ion, desymmetrized chelating ligand, 6-methyl-2,2?-bipyridine (1), gives only anti Pd· (1) 22+ complex. This regioselective complexation is applied to complementary multicomplexation of liner molecular strands: namely, a strand containing two methyl-substituted 2,2?-bipyridine units is selectively complexed on Pd(II) with its counterpart strand in which methyl groups are complementarily substituted.

The design, synthesis and structure-Activity relationship studies of some novel trisubstituted pyrimidine amide derivatives prepared as CCR4 antagonists are described. The activities of these compounds were evaluated by the CCR4-MDC chemotaxis inhibition assay. Compound 1, which we have previously reported as a potent antagonist of CCR4, was employed as the positive control. The results indicated that most of the synthesized compounds exhibited some chemotaxis inhibition activity against CCR4. Of these new compounds, compounds 6c, 12a and 12b, with IC50 values of 0.064, 0.077 and 0.069 muM, respectively, showed higher or similar activity compared with compound 1 (IC50 of 0.078 muM). These compounds provide a basis for further structural modifications. The systematic structure-Activity relationship of these trisubstituted pyrimidine amide derivatives was discussed based on the obtained experimental data. The results from the SAR study may be useful for identifying more potent CCR4 antagonists.

A study was conducted to demonstrate that H-bond based asymmetric organocatalysis can be performed under the so-called in the presence of water conditions. Nitroalkane, catalyst, dimethylcyclohexylamine, benzaldehyde and aniline were mixed to a 0C cooled and vigorously stirred aqueous solution of NaOAc/AcOH saturated with NaCl. The organic residues were taken into dichloromethane and decanted off. The combined organic fractions were dried over Na2SO4, filtered and the filtrate was concentrated. The residue was purified by flash column chromatography (silica gel) using a mixture of hexanes/ethyl acetate. From a synthetic point of view, the reaction furnishes enantioenriched b-nitroamines decorated with aromatic or aliphatic substituents at the amine center and a different set of alkyl chains or rings attached to the carbon bearing the nitro functionality. Importantly, the reaction can be scaled up without losing yield and stereoselectivity and with full recovery of the catalyst.

The design and synthesis of a novel, supramolecular allosteric catalyst system, assembled via the weak-link approach, is presented. The catalyst contains two structural Rh(I) centers in thioether- and phosphine-rich hemilabile pockets, and two functional Cr(III) centers bound within salen-based moieties. The catalytic properties of the supramolecular catalyst are compared to those of a Cr(III)-salen monomeric analogue in the context of the asymmetric ring opening of cyclohexene oxide by TMSN3. Allosteric control is afforded via reactions that occur at distal sites which open the macrocyclic cavity and facilitate the catalytic reaction. Kinetic data show a significant rate increase upon opening of the catalyst’s flexible macrocyclic cavity and enhanced selectivity and reactivity with respect to the monomeric Cr(III)-salen analogue. The work presented represents a new approach to the construction of abiotic allosteric catalysts. Copyright
