Structural and catalytic studies of lithium complexes bearing pendant aminophenolate ligands.
Lithium complexes bearing mono-anionic aminophenolate ligands are described. Reactions of ligand precursors HON(Me)Ph(OMe), HON(Me)Ph(SMe), HON(Me)C(OMe) or HON(Me)C(NMe2) [HON(Me)Ph(OMe) = (2-OMeC6H4CH2)N(Me)(CH2-2-HO-3,5-C6H2((t)Bu)2); HON(Me)Ph(SMe)= (2-SMe-C6H4CH2)N(Me)(CH2-2-HO-3,5-C6H2((t)Bu)2); HON(Me)C(OMe) = (MeOCH(2)CH2)N(Me)(CH2-2-HO-3,5-C6H2((t)Bu)2); HON(Me)C(NMe2) = (Me2NCH2CH2)N(...
متن کاملMetal ion effect on reactivity of pendant groups in functionalized macrocyclic complexes
A s donor groups of functionalized tetraazamacrocycles change the properties of the metal ion when they coordinate, so the metal ion can modify the reactivity of the functional group. Examples of Cu(I1) promoted ester and nitrile hydrolysis in the complexes 2 5 have been studied kinetically. The mechanisms of the two reactions are probably different, the nitrile being hydrolyzed to the amide by...
متن کاملSynthesis, structural characterization and NMR studies of group 10 metal complexes with macrocyclic amine N-heterocyclic carbene ligands.
A series of Ni(ii), Pd(ii) and Pt(ii) complexes [ML][PF6]2 [L = L1, M = Ni (1), Pd (2), Pt (3); L = L2, M = Ni (4), Pd (5), Pt (6)] and [Pt(L2)(acac)] (7) have been prepared by the reactions of two tetradentate macrocyclic amine-NHC ligand precursors, [H2L1][PF6]2 and [H2L2][PF6]2, with Ni(OAc)2·4H2O, Pd(OAc)2 and Pt(acac)2 in the presence of NaOAc. Complex 7 is isolated along with 6 from the s...
متن کاملDesigning new ligands: asymmetric cyclopropanation by Cu(i) complexes based on functionalised pyridine-containing macrocyclic ligands.
The synthesis and characterisation of copper(i) complexes, including two crystal structures of the new chiral pyridine-containing macrocyclic ligands (PC-type), and their use as catalysts in asymmetric cyclopropanation reactions are reported.
متن کاملSolvatochromic Properties of Heteroleptic Copper(II) Complexes Containing N,N,N',N'-Tetramethylethylenediamine and 2-Aacetylcyclopentanone Ligands
Three new heteroleptic copper(II) complexes, [(tmen)Cu(dike)H2O]X where tmen = N,N,N',N'-tetramethylethylenediamine, dike = 2-acetylcyclopentanone anion and X= ClO4- (1), Cl- (2) and Br- (3) are prepared and characterized by elemental analyses, molar conductance measurements and IR and UV-Vis spectroscopy techniques. The complex 1 is fairly soluble in various organic solvents and demonstrates d...
