Synthesis of Chiral C2-Symmetric Binucleating Ligands

The synthesis of a series of chiral enantiomerically pure C2-symmetric binucleating ligands is reported. Ligands of type 1-4, which consist of a phenolic or heterocyclic unit bridging two chiral dihydrooxazole rings, are readily accessible from

Synthesis of 3,6-Disubstituted Pyridazine Derivatives

The synthesis of pyridazine functionalized with dioximes side chains are described. Several 3,6-disubstituted pyridazine derivatives were prepared and their structures determined by spectroscopic methods (nmr, ir and ms).

Dicopper(II) Complexes of Novel Polyfunctional Pyridazines: Crystal Structure and Magnetic Properties of Bis1,N':N2,N">-bis

Two novel pyridazine ligands with 3,6-CR=NOH (R = H, H2L1; Ph, H2L2) oxime side chains were synthesised. the related copper(II) dinuclear complexes 1)2(ClO4)2(H2O)2> 1 and 2)2(ClO4)2(MeOH)n> 2 were obtained subsequently.The crystal structure of 1 was determined: space group P21/n, a=12.031(6), b=9.517(4), c=9.973(5) Angstroem, β=100.16 deg and Z=2.The copper(II) ions of the binuclear unit are bridged by the two diazine fragments of the two essentially planar tetradentate ligands with the oxime nitrogen atoms completing the equatorial co-ordination.Two intra-complex hydrogen bridges link the terminal oximato moieties to give dinucleating macrocyclic complexes.In complexes 1 and 2 the copper(II) is in a classical 4 + 2 environment.The magnetic properties of those compounds revealed a spin-singlet ground state in each case.The singlet-triplet energy gaps were found to be -536(2) for 1 and -545(4) cm-1 for 2.The low-lying states of the complexes are discussed in relation to the nearly planar structure of the macrocyclic complexes.
