Role of the Ligand and of the Size and Flexibility of the Palladium−Ancillary Ligand Cycle on the Reactivity of Substituted Alkynes toward Palladium(0) Complexes Bearing Potentially Terdentate Nitrogen−Sulfur−Nitrogen or Nitrogen−Nitrogen−Nitrogen Ligands: Kinetic and Structural Study
palladium(0) complexes bearing potentiallyterdentateligands and dimethyl acetylenedicarboxylate (DMA) to give the corresponding palladacyclopentadiene complexes was studied under kinetic conditions. The reactivity of the complexes was markedly influenced by the nature of the ancillary ligand. Thus, when pyridyldithioether (SNS) and dipyridylthioether (NSN) ligands are used, the reactivity and the

Copper(I) iodide reacts with 8-((2-pyridylmethyl)thio)quinoline (MPTQ) to give the tetranuclear cluster complex [Cu4I4(MPTQ)2] which has been structurally characterized, showing that the Cu4I4 core exists in a distorted chair-like structure with four copper atoms forming parallelogram which is bridged by iodine atoms on each short sides, by S, N-MPTQ on each long sides and with two additional iodine
Synthesis, Stability Constant Determination, and Structural Study of Some Complexes of a Zinc Triad Containing Pyridyl‐amine‐quinoline and Pyridyl‐thio‐quinoline
these complexes undergo NMR-scale fast fluxional rearrangement in solution. Some structural X-ray diffractometric studies were also performed and the ensuing data confirm the surmised structures and the solution rearrangement in the case of monochelate substrates and of one Hg derivative, respectively. The equilibrium constants of formation in the case of monochelate derivatives were also determined in

semirigid tridentate 8-(2-pyridinylmethylthio)quinoline ligand (Q1) is shown to form the structurally characterized transition metal complexes [Cu(Q1)Cl2] (1), [Co(Q1)(NO3)2] (2), [Cd(Q1)(NO3)2] (3), [Cd(Q1)I2] (4). [Cu(Q1)2](BF4)2·(H2O)2 (5), [Cu(Q1)2](ClO4)2·(CH3COCH3)2 (6), [Zn(Q1)2](ClO4)2(H2O)2 (7), [Cd2(Q1)2Br4] (8), [Ag2(Q1)2(ClO4)2] (9), and [Ag2(Q1)2(NO3)2] (10). Four types of structures have been
