Synthesis and characterization of copper(ii) complexes with multidentate ligands as catalysts for the direct hydroxylation of benzene to phenol.
Four copper(ii) complexes with multidentate ligands, ([CuL1Cl2]), ([Cu(HL2)Cl2]), ([Cu2(L2)2](ClO4)2) and ([CuL3(HOCH3)ClO4]) {L1 = N,N-bis((pyridin-2-yl)methyl) prop-2-yn-1-amine, HL2 = 2-((((1-methyl-1H-imidazol-2-yl)methyl)(pyridin-2-ylmethyl)amino)methyl)phenol and HL3 = 2-((((1-methyl-1H-imidazol-2-yl)methyl)(pyridin-2-ylmethyl)amino)methyl)-2-t-butyl-phenol} are reported. The complexes we...
متن کاملCopper(I) and copper(II) complexes with pyrazine-containing pyridylalkylamide ligands N-(pyridin-2-ylmethyl)pyrazine-2-carboxamide and N-(2-(pyridin-2-yl)ethyl)pyrazine-2-carboxamide
Four copper(II) complexes and one copper(I) complex with pyridine-containing pyridylalkylamide ligands N-(pyridin-2-ylmethyl)pyrazine-2-carboxamide (HL) and N-(2-(pyridin-2-yl)ethyl)pyrazine2-carboxamide (HL) were synthesized and characterized. The X-ray crystal structures of [Cu2(L )2(4,4ʹ-bipy)(OTf )2] (1, OTf = trifluoromethanesulfonate, 4,4ʹ-bipy = 4,4ʹ-bipyridine) and [Cu(L)(py)2]OTf·H2O (...
متن کاملModular syntheses of multidentate ligands with variable N-donors: applications to tri- and tetracopper(I) complexes.
A general method for the preparation of multidentate ligands comprised of a multi-imine platform derived from 1,1,1-tris(aminomethyl)ethane or tris(aminoethyl)amine connected to bi- and tridentate N-donor chelates has been developed. The feasibility of the method has been demonstrated through the synthesis and characterization of a large set of these ligand types. Complexation to Cu(I) was acco...
متن کاملMultidentate thioether ligands coating gold nanoparticles.
The design and synthesis of oligomeric ligands based on benzylic thioethers is presented together with their ability to enwrap and stabilize gold nanoparticles with diameters below 2 nm, which become--with increasing length of the oligomer--more monodisperse and stable.
متن کاملCopper(II) complexes of tetradentate thioether-oxime ligands
Two dinuclear copper(II) thioether-oxime complexes ([Cu(DtdoH)]2(ClO4)2 and [Cu(DtudH)]2(ClO4)2 Æ 2CH3OH) have been synthesized. [Cu(DtdoH)]2(ClO4)2 reacted with excess BF3 Æ OEt2 to yield [Cu(Thyclops)]ClO4, a BF2 þ-macrocyclized di-oxime. [Cu(DtdoH)]2(ClO4)2 and [Cu(DtudH)]2(ClO4)2 Æ 2CH3OH are the first representatives of copper(II) thioether oximes which exhibit the classical out-of-plane o...
