Transitionmetal complexes with pyrazole-based ligands: Part 21. Thermal decomposition of copper and cobalt halide complexes with 3,5-dimethyl-1- thiocarboxamidepyrazole

The thermal decomposition of Cu2L2Cl4, Cu2L2Cl2, Cu2L2Br 2 and Co2L2Cl4 complexes (L=3,5-dimethyl-1-thiocarboxamidepyrazole) is described. The influence of the central ion to ligand mole ratio on the course of complex formation is examined in reaction of L with copper(II) chloride. In Cu(II):L mole ratio of 1:1, in methanolic solution the reaction yields to yellow-green Cu2L 2Cl4 crystals. In the filtrate a thermodynamically more stable orange Cu2L2Cl2 copper(I) complex is forming. With a Cu(II):L mole ratio of 1:2 only the latter compound is obtained. The composition and the structure of the compounds have been determined on the basis of customary methods. On the basis of FTIR spectrum of the intermediate which is forming during the thermal decomposition of Cu2L 2Cl2 a decomposition mechanism is proposed.

The use of copper-based antifoulings on aluminium ship hulls

Copper, most commonly in the form of copper oxide, is used in the majority of marine antifoulings globally, but some paint companies do not allow their copper oxide based antifoulings to be used on aluminium hulls. This is because aluminium is more anodic in the electrochemical series than copper and if the two are in direct connect in sea water, the aluminium will corrode away. This galvanic reaction only occurs if copper metal is in direct contact with aluminium, and since modern copper oxide based antifoulings contain virtually no metallic copper there appears to be no valid reason for the ultra-cautious approach regarding the use of copper oxide based antifoulings on aluminium hulls. A number of different copper-based commercial antifoulings were applied on suitably prepared Marine-grade aluminium panels, along with an un-coated control panel. The panels were immersed in seawater. Furthermore a laboratory experiment was also undertaken where coated aluminium panels were submerged in a salt water solution as a controlled experiment. All the samples were then analysed using electron microscopy. Copper leaching out of copper oxide based antifoulings had no effect on the corrosion of Marine-grade aluminium.

Copper-catalyzed intramolecular C(sp3)-H and C(sp2)-H amidation by oxidative cyclization

The first copper-catalyzed intramolecular C(sp3)-H and C(sp 2)-H oxidative amidation has been developed. Using a Cu(OAc) 2 catalyst and an Ag2CO3 oxidant in dichloroethane solvent, C(sp3)-H amidation proceeded at a terminal methyl group, as well as at the internal benzylic position of an alkyl chain. This reaction has a broad substrate scope, and various beta-lactams were obtained in excellent yield, even on gram scale. Use of CuCl2 and Ag2CO3 under an O2 atmosphere in dimethyl sulfoxide, however, leads to 2-indolinone selectively by C(sp2)-H amidation. Kinetic isotope effect (KIE) studies indicated that C-H bond activation is the rate-determining step. The 5-methoxyquinolyl directing group could be removed by oxidation.

Mechanistic studies of copper thin-film growth from CuI and CuII beta-diketonates

The kinetics and mechanism of copper film growth from the reactions of bis(acetylacetonato)copper(II), bis(hexafluoroacetylacetonato)copper(II), and (vinyltrimethylsilane)(hexafluoroacetylacetonato)copper(I) (Cu(hfac)(vtms)) with copper single crystal surfaces were investigated. Experiments were performed using vibrational spectroscopy (reflection infrared and high-resolution electron energy loss spectroscopies) as well as mass spectrometry (temperature-programmed desorption and integrated desorption mass spectrometries). Both ligand desorption and dissociation were observed upon pyrolysis of these molecules under ultra-high-vacuum conditions. We demonstrate that adsorbed beta-diketonate ligands decompose in a stepwise fashion at temperatures above ?375 K to yield adsorbed CF3 and ketenylidene (?C-C?O) intermediates. These further decompose above ?500 K to leave surface carbon, a major contaminant in copper films grown from CuII beta-diketonates. Clean films can be grown from the pyrolysis of Cu(hfac)(vtms) at pressures above 10-5 Torr, however. The implications of our results relative to the mechanism of copper film growth at elevated pressures are also discussed.

Spontaneous assembly of organic thiocyanates on gold sufaces. Alternative precursors for gold thiolate assemblies

Thiolate self-assembly on gold has proven to be a valuable technique for assembling monolayers on a wide variety of substrates. However, the oxidative instability of the thiols, especially aromatic thiols and alpha,omega-dithiols, presents several difficulties. Shown here is that thiocyanates, easily synthesized stable thiol derivatives, can be directly assembled on gold surfaces with no auxiliary reagents required. Assembly is complete in 24 h and leaves a similar gold thiolate structure as seen in typical thiol self-assembled monolayers. Copyright
