Oxyhalogen–Sulfur Chemistry: Kinetics and Mechanism of Oxidation of Tiopronin by Acidified Bromate and Aqueous Bromine 
Wilbes Mbiya, Risikat Adigun, Thai Tran, Yadana Htwe and Reuben H. Simoyi

Biologically active compounds containing a thiol group are oxidatively bioactivated in physiological environment. This study involves the putative mechanism of oxidative bioactivation of tiopronin. Tiopronin, N-2-(mercaptopropionyl)glycine (MPG), is a glycine derivative with a thiol group that has properties similar to those of penicillamine, one of the flagship antibiotics.

Nanoporous Platinum Electrodes as Substrates for Metal Oxide-Supported Noble Metal Electrocatalytic Nanoparticles: Synergistic Effects During Electrooxidation of Ethanol 
Iwona A. Rutkowska, Margaretta D. Koster, Gary J. Blanchard and Pawel J. Kulesza

Immobilization of WO3- or TiO2-supported PtRu nanoparticles onto the nanoporous platinized substrates leads to the formation of multifunctional electrocatalytic systems reactive towards oxidation of ethanol at fairly low potentials (<0.4 V vs RHE). Among the important issues are the presence of –OH groups at metal nanostructures, including oxidative removal of –CO adsorbates.

Synergistic Antibacterial Activity of Nanohybrid Materials ZnO–Ag and ZnO–Au: Synthesis, Characterization, and Comparative Analysis of Undoped and Doped ZnO Nanoparticles 
Adriana Berenice Pérez Jiménez, Carlos Alberto Huerta Aguilar, Jorge Manuel Vázquez Ramos and Pandiyan Thangarasu

Because ZnO and Ag nanoparticles (NPs) effectively inhibit foodborne pathogens, both metals are expected to produce a more effective inhibitor as a result of hybrid properties. It has been reported that Ag-doped ZnO NPs and ZnO NPs do not show much difference in antibacterial activities, but show an increase in bacterial inhibition. To explain why doping of Ag NPs, unlike Au NPs, in ZnO NPs influences the antibacterial activities, ZnO, ZnO–Ag, and ZnO–Au NPs were synthesized.

Probing Mechanisms of Aryl–Aryl Bond Cleavages under Flash Vacuum Pyrolysis Conditions 
Edward A. Jackson, Xiang Xue, Hee Yeon Cho and Lawrence T. Scott

Flash vacuum pyrolysis (FVP) of phenyl-substituted polycyclic aromatic hydrocarbons (PAHs) promotes the formation of new rings by thermal cyclodehydrogenation reactions; however, such reactions are often accompanied by competitive loss of the phenyl group. Such ‘phenyl loss’ reactions cleave strong aryl–aryl bonds and are therefore important to understand. As probes for the mechanism(s) involved in the ‘phenyl loss’ reaction, FVP experiments were conducted with several phenyl-substituted PAHs and larger biaryls.

Trifluoromethylphenylcarbenes. Carbene-Carbene Interconversion on the Singlet Energy Surface and Rearrangement to Trifluorobenzocyclobutene, Trifluorostyrene, and Trifluoromethylfulvenallenes 
Rodney J. Blanch and Curt Wentrup

The four isomeric α-, ortho-, meta-, and para-trifluoromethylphenylcarbenes interconvert thermally and in part photochemically. Electron spin resonance investigations indicate that carbene-carbene rearrangement takes place on the singlet energy surface and is competitive with intersystem crossing to the triplet state. Flash vacuum thermolysis of the α-trifluoromethylphenylcarbene results in rearrangement to trifluorobenzocyclobutene and trifluorostyrene.

pp. 1044-1055

The redox-active guanidine-functionalized 1,2,4,5-tetrakis(N,N’-diisopropylguanidino)benzene was recently shown to be a redox-active switch, and reversibly forms hydrogen-bond aggregates upon two-electron oxidation. In this work, the hydrogen-bond motifs in the first coordination compounds with the neutral and oxidized guanidine as ligand are reported.

Zoran Glasovac and Mirjana Eckert-Maksić
pp. 1056-1062

Predicting acid/base properties of unknown molecules using data which can be tabulated is an everlasting goal in chemistry. In this sense, molecules containing intramolecular hydrogen bond are especially problematic. Our results show very good correlation of GB against pKHB and newly introduced σ4B parameter for a series of guanidine bases with intramolecular hydrogen bond.

pp. 1100-1109

The general principle of asymmetric organocatalysis using chiral bicyclic guanidine as a bifunctional catalyst is illustrated in a density functional theory study of [5,5]-bicyclic guanidine-catalyzed Michael addition of dimethyl malonate to cyclopentenone. Two types of bifunctional activation modes were examined. The calculated enantioselectivity is in excellent accord with experiment result.
