Discrete dinuclear and polymeric copper(I) cations bridged by 4,4?-bipyridine, trans-1,2-bis(4-pyridyl)ethene or bis(4-pyridyl) disulfide

Treatment of an acetonitrile solution of copper(I) tetrafluoroborate and 4,4?-bipyridine (4,4?-bipy) with 2-cyanoguanidine (cnge) yielded [{Cu(cnge)2}2(mu-4,4?-bipy)][BF4] 2·MeCN 1. Structural analysis revealed a planar dinuclear cation containing two, three-co-ordinate T-shaped copper centres bridged by 4,4?-bipy and terminally co-ordinated by two cnge molecules. In the absence of cnge but with an excess of copper(I), the product was [Cu(4,4?-bipy)(MeCN)2]BF4 2, structural analysis of which revealed a one-dimensional polymeric cationic zigzag chain, based on tetrahedral copper(I) atoms bridged by 4,4?-bipy and terminally co-ordinated by two MeCN molecules. The same reaction mixture but with an excess of 4,4?-bipy gave [Cu(4,4?-bipy)2]BF4·MeCN 3. The corresponding trans-1,2-bis(4-pyridyl)ethene (bpe) systems yielded the analogous [{Cu(cnge)2}2(mu-bpe)][BF4] 2·6MeCN 4, [Cu(bpe)(MeCN)2]BF4 5 and [Cu(bpe)2]BF4 6, respectively. Only one product has been isolated from the corresponding bis(4-pyridyl) disulfide (bpds) systems, [Cu(bpds)(MeCN)2]BF4 7. Attempts to produce copper(I) derivatives of 3,6-bis(imidazolyl)pyridazine (bimpydz) were unsuccessful, the copper(II) product, Cu(bimpydz)(MeCN)2(BF4)2 8, invariably being formed. Whereas the [{Cu(cnge)2}2(diimine)]2+ and [Cu(diimine)(MeCN)2]+ cations reacted with NOBF4 and NBut4NO2 forming copper(II) oxidation products, the [Cu(diimine)2]+ cations were unreactive.

New ternary ligands consisting of an N4 bridging ligand and two terpyridines, and their Co(ii) and Ni(ii) dinuclear complexes. Structure, redox properties, and reaction with acid

Two ternary ligands consisting of two 2,2?:6?,2??- terpyridines and one N4-quadridentate mu2,eta2- bridging ligand were synthesized. The N4 bridge is 1,4-bis(2-pyridyl)phthalazine in ligand 1, and 3,6-bis(2-pyridyl)pyridazine in ligand 2. Two Co(ii) dinuclear complexes [(1)Co2(mu-OH)]3+ and [(2)Co 2(mu-OH)]3+, and one Ni(ii) dinuclear complex [(1)Ni2(mu-Cl)]3+ were obtained. In the crystal structures of [(1)Co2(mu-OH)]3+ and [(1)Ni 2(mu-Cl)]3+, two pyridine rings are twisted around the pyridine-phthalazine bonds to avoid steric repulsion between the hydrogen atoms. The pyridine rings also showed a significant tilt from the octahedral coordination plane, which causes the large positive shift of the first reduction potentials. Upon the addition of a proton, the cobalt dinuclear complexes can release one cobalt ion selectively, and the dinuclear complexes can be easily restored by the addition of a tertiary amine.

Synthesis of 3,6-Dichloro-4-(2-chloro-1,1-dimethylethyl)pyridazine

3,6-Dichloro-4-(2-chloro-1,1-dimethylethyl)pyridazine (3) is a systemic plant fungicide whose synthesis by several routes is described.Free-radical alkylations of 3,6-dichloropyridazine (1) gave either the 4-tert-butyl derivative 2 or the alcohol 3,6-dichloro-beta,beta-dimethyl-4-pyridazineethanol (24).Pyridazine (2) must be subjected to a free-radical chlorination, which resulted in other products, but alcohol 24 could be smoothly converted to 3.Alternatively, the pyridazine ring was constructed with the side chain preattached by utilizing lactone intermediates 10 or 18.The lactone 10 with hydrazine yielded the ether 11, and chlorination with ether cleavage proceeded to 3.Lactone 20 could not be transformed to 3.
