Stability, Electronic Spectra, and Structure of Transition-metal Ion Complexes of a Novel Mixed-donor (Nitrogen-Sulphur) Macrocycle, 1-Thia-4,7-diazacyclononane

The synthesis of the novel ligand 1-thia-4,7-diazacyclononane (L1) is described.A potentiometric study yields pK1 as 9.67, and pK2 as 3.98 in 0.1 mol dm-3 NaNO3 at 25 deg C; complex-formation constant

Dinuclear CuIIMII (M = Co, Ni, Cu or Zn) and CuIICuI Complexes of a Phenol-based Dinucleating Macrocycle with Dissimilar N2O2 and N2O2S Sites

A dinucleating macrocycle H2L with two 2,6-bis(iminomethyl)-4-methylphenolate entities combined through two lateral chains, CH2CH2 and CH2CH2SCH2CH2, at the imino nitrogens has been obtained as a mononuclear copper(II) complex 2

Electrochemical CO2 Reduction-The Effect of Chalcogenide Exchange in Ni-Isocyclam Complexes

Among the numerous homogeneous electrochemical CO2 reduction catalysts, [Ni(cyclam)]2+ is known as one of the most potent catalysts. Likewise, [Ni(isocyclam)]2+ was reported to enable electrochemical CO2 conversion but has received significantly less attention. However, for both catalysts, a purposeful substitution of a single nitrogen donor group by chalcogen atoms was never reported. In this work, we report a series of isocyclam-based Ni complexes with {ON3}, {SN3}, {SeN3}, and {N4} moieties and investigated the influence of nitrogen/chalcogen substitution on electrochemical CO2 reduction. While [Ni(isocyclam)]2+ showed the highest selectivity toward CO2 reduction within this series with a Faradaic efficiency of 86% for the generation of CO at an overpotential of-1.20 V and acts as a homogeneous catalyst, the O-and S-containing Ni complexes revealed comparable catalytic activities at ca. 0.3 V milder overpotential but tend to form deposits on the electrode, acting as precursors for a heterogeneous catalysis. Moreover, the heterogeneous species generated from the O-and S-containing complexes enable a catalytic hydride transfer to acetonitrile, resulting in the generation of acetaldehyde. The incorporation of selenium, however, resulted in loss of CO2 reduction activity, mainly leading to hydrogen generation that is also catalyzed by a heterogeneous electrodeposit.

Straightforward approach to efficient oxidative DNA cleaving agents based on Cu(ii) complexes of heterosubstituted cyclens

The Cu(ii) complexes of cyclen and two of its heterosubstituted analogues were shown to be efficient oxidative DNA cleavers. The reactivity strongly depends on the heteroatom inserted into the macrocycle (O > S > N). The Royal Society of Chemistry 2013.
