Attempts to extend the LDA-mediated 1-aminoisoquinoline arynic synthesis to 1,2-dibromo-3,4,5,6-tetramethylbenzene (1a) and the hetarylacetonitriles 2- (2a) and 3-pyridylacetonitrile (2b), 2- (2c) and 3-thiopheneacetonitrile (2d), and 2-benzimidizoylacetonitrile (2e) failed; only rearranged 2-hetarylmethyl-3,4,5,6-tetramethylbenzonitriles (3aa-3ae) were obtained.Additionally, the reaction of 1-chloro-2,5-dimethylbenzene (1b), 2-bromo-4-methylanisole (1c), bromobenzene (1d), 2-bromoanisole (1e), and 1-bromo-2,5-dimethoxybenzene (1f) with 2a-e gave rearranged nitriles (3) by the tandem addition-rearrangement aryne pathway and/or aryne arylated nitriles (4) by the aryne arylation pathway.By evaluating product 3:4 ratios from these reactions, an assessment of the influence of the nature of the haloarenes and hetarylacetonitriles on the competing tandem addition-rearrangement and aryne arylation pathways was made, which showed that the preference of the haloarenes for the rearrangement pathway to be 1a ca. 1b > 1c > 1d > 1e > 1f and that for the hetarylacetonitriles to be 2c ca. 2d > 2b > 2a > 2e.An explanation in terms of the influence of the haloarene substituents on the ring-closure step of the rearrangement pathway and the heterocyclic ring of the hetarylacetonitrile on the proton abstraction step of the alternate aryne arylation pathway is presented.

Three new unsymmetrical compartmental dinucleating ligands, 4-bromo-2-(4-methylpiperazin-1-ylmethyl)-6-[{2-(1-piperidyl)ethyl}aminomethyl] phenol (HL1), 4-bromo-2-(4-methylpiperazin-1-ylmethyl)-6-[{2-(morpholin-4-yl) ethyl}aminomethyl]phenol (HL2), and 4-bromo-2-(4-methylpiper-azin-1-ylmethyl)-6- [{2-(thiomorpholin-4-yl)ethyl}aminomethyl]phenol (HL3), have been synthesized in order to model the active site of type 3 copper proteins. The dicopper(II) complexes of these ligands give first hints about the influence of a thioether group close to the metal site. The bromophenol-based ligands have one piperazine arm and one other bidentate arm in positions 2 and 6 of the phenolic ring, respectively. With each ligand a dinuclear copper(II) complex was prepared and structurally characterized. The copper ions were found to have square pyramidal environments and a mixture of endogenous phenoxo and exogenous acetate bridging. The influence of a heteroatom in one arm of the ligand on catecholase activity and speciation in solution was studied by UV/Vis spectroscopy, ESI-MS experiments and, DFT calculations.
