چکیده
Z. Naturforsch. 53 b, 1379-1385 (1998); received June 26, 1998 Mononuclear Complexes, Nickel, Amine-Thiolate Ligands, Solid-State Structures, SolutionState Structures The syntheses of N-alkylated derivatives of the arenethiol 4-terf-butyl-2,6-(diaminomethyl)thiophenol and their coordination properties are reported. Compounds 4-terf-butyl-2,6-di(/V-isopropyl-aminomethyl)thiophenol (3) and 4-terf-butyl-2-(AMsopropyl-aminomethyl)-6-hydroxymethylthiophenol (6 ) react with Ni(II) salts to give compounds of composition [Ni(3 )2]-2HC1 (7) and [Ni(6 )2] (8 ). The solidand solution-state structures of both complexes consist of mononuclear complexes with four-coordinate nickel(II) ions in approximately planar transN2S2 coordination environments. In contrast to the parent arenethiol 4a, the sterically more encumbered ligands do not form dinuclear complexes.

Some Synthetic Applications of 3 , 4 - disubstituted Indoles Generated via Zirconocene - Stabilized Benzyne Complexes
A method previously developed for the regiospecific synthesis of polysubstituted indolines and indoles has been investigated for its utility in organic synthesis. The method relies on the regiospecific generation of zirconocene-stabilized benzyne complexes from N-allyl-2-bromoaniline derivatives. These complexes undergo an intramolecular olefin insertion to provide 5,5,6-tricyclic indoline zirc...
متن کاملBis(Imino) Pyridyl Iron Complexes: the Effect of Polymerization Conditions on Activities and Thermal Behaviors of Polyethylene
Two late transition metal catalysts based on 2,6-bis(imino)pyridine iron(II) were synthesized by introducing methyl substitution (catalyst A) and t-Butyl substitution (catalyst B) at the ortho position of the aryl rings of the ligand. Comparative ethylene polymerizations using the catalysts showed quiet different behaviors. The activity of catalyst A was higher than that of catalyst B in all of...
متن کاملUseful Method for the Preparation of Low-Coordinate Nickel(I) Complexes via Transformations of the Ni(I) Bis(amido) Complex K{Ni[N(SiMe3)(2,6-iPr2-C6H3)]2}
A convenient method of preparing two- and three-coordinate Ni(I) complexes of the form L-NiI-X (L = P t Bu3, P i Pr3, DPPE, NHC; X = -N(SiMe3)(2,6- i Pr-C6H3), -O(2,6- t Bu2-4-Me-C6H2)) is reported. Protonation of the easily prepared anionic Ni(I) bis(amido) complex K{Ni[N(SiMe3)(2,6- i Pr-C6H3)]2} in the presence of an appropriate L-type ligand results in loss of HN(SiMe3)(2,6- i Pr-C6H3) and ...
متن کاملMechanistic Studies of Dinuclear Metalloenzymes - A Model Approach
With the goal to study the mechanisms of dinuclear metalloenzymes, new synthetic and computational models for such proteins were prepared and studied. Multidentate ligands based on a central phenolate and with imidazoleand carboxylate-containing donor moieties were synthesized to simulate carboxylate-rich ligand environments. The two ligands that were found to be the most useful, were the symme...
