Reference of 589-87-7, New discoveries in chemical research and development in 2021.The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 589-87-7, Name is 1-Bromo-4-iodobenzene, SMILES is C1=CC(=CC=C1Br)I, molecular formula is C6H4BrI, belongs to thiomorpholine compound. In an article, author is Li, YX, introduce new discover of the category.
A chelating ligand, 2,6-bis(thiomorpholinomethyl)pyridine (L), was synthesised. Its palladium(II), copper(II) and nickel(II) complexes of the formula ML(NO3)(2), (M = Pd, Cu and Ni), were prepared and characterised. The molecular structures of the three complexes were determined by X-ray diffraction. In all the compounds prepared the ligand acts in a tridentate fashion using its three N atoms while the two S atoms remain free. The Pd complex possesses a distorted square planar coordination geometry with one of the two nitrate groups coordinating as a unidentate ligand and the other ionic. The Pd-N(pyridine) bond length is 1.857(4) Angstrom, which is believed to be the shortest Pd-N separation ever observed. In the Cu complex, the copper atom is five-coordinated in a distorted square planar arrangement with the two nitrate groups acting as unidentate ligands and occupying the apex and one equatorial position. The Ni complex has a distorted octahedral coordination sphere; one nitrate group behaves in a chelating fashion and the other unidentate. (C) 1998 Elsevier Science S.A. All rights reserved.
