Labile Cu(I) catalyst/spectator Cu(II) species in copper-catalyzed C-C coupling reaction: Operando IR, in situ XANES/EXAFS evidence and kinetic investigations

Insights toward the Cu-catalyzed C-C coupling reaction were investigated through operando IR and in situ X-ray absorption near-edge structure/extended X-ray absorption fine structure. It was found that the Cu(I) complex formed from the reaction of CuI with β-diketone nucleophile was liable under the cross-coupling conditions, which is usually considered as active catalytic species. This labile Cu(I) complex could rapidly disproportionate to the spectator Cu(II) and Cu(0) species under the reaction conditions, which was an off-cycle process. In this copper-catalyzed C-C coupling reaction, β-diketone might act both as the substrate and the ligand.

Electrophilicities of bissulfonyl ethylenes

Kinetics of the reactions of bissulfonyl ethylenes with various carbanions, a sulfur ylide, and siloxyalkenes have been investigated photometrically at 20°C. The second-order rate constants have been combined with the known nucleophile- specific parameters N and sN for the nucleophiles to calculate the empirical electrophilicity parameters E of bissulfonyl ethylenes according to the linear free energy relationship log k(20°C)=s N(N+E). Structure-reactivity relationships are discussed, and it is shown that the electrophilicity parameters E derived in this work can be employed to define the synthetic potential of bissulfonyl ethylenes as Michael acceptors.

Synthesis of ruthenium(iii) and rhodium(iii) tris-acetylacetonates and palladium(ii) bis-ketoiminate using microwave heating

Preparation of ruthenium(iii) and rhodium(iii) tris-acetylacetonates and palladium(ii) bisketoiminate (Pd(i-acac)2) under microwave irradiation using different synthetic conditions, both in the solid-phase and in solution, was studied with precise control of parameters. In the solid-phase systems, the preparation of the target product was hindered. The efficiency of the microwave heating increased when liquid phases of the reagent mixtures were used. For Pd(i-acac)2, the highest yield was achieved under elevated temperature of the process, with the reaction time decreasing to several minutes. A laboratory procedure for the microwave synthesis of ruthenium(iii) and rhodium(iii) tris-acetylacetonates and palladium(ii) bis-ketoiminate in aqueous solutions was developed, which allowed us to obtain them in 85, 55, and 80% yields, respectively. These yields are higher than those reported in the literature, with the process becoming considerably less time consuming and laborious.

Electrophilicities of trans-β-nitrostyrenes

The kinetics of the reactions of the trans-β-nitrostyrenes 1a-f with the acceptor-substituted carbanions 2a-h have been determined in dimethyl sulfoxide solution at 20 °C. The resulting second-order rate constants were employed to determine the electrophile-specific reactivity parameters E of the trans-β-nitrostyrenes according to the correlation equation log k 2(20 °C) = sN(N + E). The E parameters range from -12 to -15 on our empirical electrophilicity scale (www.cup.lmu.de/oc/mayr/DBintro. html). The second-order rate constants for the reactions of trans-β- nitrostyrenes with some enamines were measured and found to agree with those calculated from the electrophilicity parameters E determined in this work and the previously published N and sN parameters for enamines.

Mechanistic studies on the thermal and photochemical decomposition of dimethyl(2,4-pentanedionato)gold(III) in solution

Mechanisms of the thermal and photochemical decomposition of dimethyl(2,4-pentanedionato)gold were examined by UV-visible and 1H NMR spectroscopies in solution. The formation of gold mirrors results from both the thermal and photochemical decomposition reactions. The thermal decomposition reaction is extremely solvent dependent and is not observed in non-coordinating, non-polar solvents (i.e. cyclohexane). The kinetics for thermal decomposition are observed to be first-order in gold complex disappearance although the solvent plays a critical role in the decomposition process. Decomposition by reductive elimination of ethane and protonation of the 2,4-pentandionate ligand are major reaction modes. The mechanism for reductive elimination is examined by deuterium labeling with the perdeuteriodimethylgold compound. The formation of ethane-d3 and traces of methane by reaction from the 50:50 mixture of (dimethyl-d0)-and (dimethyl-d6)(2,4-pentanedionato)gold indicates that free radicals are formed from the homolysis of gold-methyl bonds. On the basis of the ratio of ethane-d0 to ethane-d3, however, the reaction is believed to proceed predominantly via a concerted reductive elimination and, to a lesser extent, a free-radical mechanism simultaneously. On the other hand, the photochemical decomposition produces more 3-methyl-2,4-pentanedione and less ethane. In labeling studies, the ratio of ethane-d0 to ethane-d3 is also decreased and is indicative of the greater radical nature of the photolytic mechanism. The UV photolysis does not show the same solvent dependence to reaction as the pyrolysis does, although the observed product ratios do vary with solvent. Thus, solvent-cage effects may be important to the decomposition process.
