In the title compound, [Ti2(C16H14N2O2)2O2]·2CHCl3, the Ti(IV) atom in the centrosymmetric complex has a distorted octa-hedral N2O4 coordination environment and is linked via two μ2-oxido bridges into a dinuclear centrosymmetric com-plex, with a Ti⋯Ti separation of 2.7794 (8) Å. In the salen (N,N'-ethyl-enebis(salicyl-imine)) ligand, the two salicyl-imine units make a dihedral angle of 45.31 (5...
A new iridium catalyst containing an imine-diphosphine ligand has been developed, which showed high efficiency for the hydrogenation of CO2 to formate (yield up to 99%, TON up to 450 000). A possible catalytic mechanism is proposed, in which the imine group of the catalyst plays a key role in the cleavage of H2 and the activation of CO2.
The complex molecule in the title compound, [NiBr2(C36H40N2)], has mirror symmetry. The Ni(II) atom and two Br atoms are located on the mirror plane. The Ni(II) atom is four-coordinated by the two Br atoms and two N atoms from an N,N'-bis(2,6-diethyl-4-phenyl-phen-yl)butane-2,3-di-imine ligand in a distorted tetra-hedral geometry. The dihedral angle formed between the two adjacent benzene rings...
An efficient synthesis of 5-bromo-2-methoxy-6-methylaminopyridine-3-carboxylic acid (1), a carboxylic acid moiety of a potent dopamine D2 and D3 and serotonin-3 (5-HT3) receptors antagonist, (R)-5-bromo-N-(1-ethyl-4-methylhexahydro-1 ,4-diazepin-6-yl)-2-methoxy-6-methylaminopyridine-3-carboxamide, is described. Reaction of methyl 2,6-difluoropyridine-3-carboxylate (12) with methylamine in EtOH ...
Novel silylium ions with N-heterocyclic imines were successfully synthesized. The reaction of trimethylsilyl imidazolin-2-imine Me₃SiNIPr (NIPr = bis(2,6-diisopropylphenyl)-imidazolin-2-imino) with B(C₆F₅)₃ leads to dimeric imino-substituted silylium ions through a methyl group abstraction on the silicon atom. Meanwhile, the intermolecular imino-coordinated silylium ion is formed by using the l...
Inhibition of the catalytic subunit of the heterodimeric methionine S-adenosyl transferase-2 (MAT2A) with fluorinated N,N-dialkylaminostilbenes (FIDAS agents) offers a potential avenue for the treatment of liver and colorectal cancers where upregulation of this enzyme occurs. A study of structure-activity relationships led to the identification of the most active compounds as those with (1) eit...
