Decarbonylative CC Bond‐Forming Reactions of Saccharins by Nickel Catalysis: Homocoupling and Cycloaddition
Authors: Mi Pengbing , Liao Peiqiu , Tu Tao , Bi Xihe 
Published: February 2015

AbstractDecarbonylation of saccharins by nickel catalysis enables two kinds of CC bond‐forming reactions; homocoupling of saccharins to form biaryls and cycloaddition with alkynes to form benzosultams. The former represents the first reported nickel‐catalyzed decarbonylative CC homocoupling reaction, whereas the latter constitutes a powerful method to pharmaceutically relevant benzosultams. The reactions proceed with good functional‐group tolerance and excellent regioselectivity.
Photobiochemical Production of Carbon Monoxide by Thermus thermophilus ba3‐Cytochrome c Oxidase
Authors: Koutsoupakis Constantinos , Soulimane Tewfik , Varotsis Constantinos 
Published: February 2015

AbstractWe report the photobiochemical production of carbon monoxide by a terminal ba3‐cytochrome c oxidase from T. thermophilus HB8. FTIR and time‐resolved step‐scan FTIR spectroscopies were combined to probe this process and also monitor the concomitant binding of the produced gas to other intact ba3 molecules forming the ba3–CO complex. The activation of this mechanism by ba3‐oxidase under visible excitation raises the question as to whether such a mechanism is physiologically relevant to the extreme environment in which it operates.

AbstractAlkylzinc alkoxides, [RZnOR′]4, have received much attention as efficient precursors of ZnO nanocrystals (NCs), and their “Zn4O4” heterocubane core has been regarded as a “preorganized ZnO”. A comprehensive investigation of the synthesis and characterization of a new family of tert‐butyl(tert‐butoxy)zinc hydroxides, [(tBu)4Zn4(μ3‐OtBu)x(μ3‐OH)4−x], as model single‐source precursors of ZnO NCs is reported. The direct reaction between well‐defined [tBuZnOH]6 (16) and [tBuZnOtBu]4 (24) in various molar ratios allows the isolation of new mixed cubane aggregates as crystalline solids in a high yield: [(tBu)4Zn4(μ3‐OtBu)3(μ3‐OH)] (3), [(tBu)4Zn4(μ3‐OtBu)2(μ3‐OH)2] (4), [(tBu)4Zn4(μ3‐OtBu)(μ3‐OH)3] (5). The resulting products were characterized in solution by 1H NMR and IR spectroscopy, and in the solid state by single‐crystal X‐ray diffraction. The thermal transformations of 2–5 were monitored by in situ variable‐temperature powder X‐ray diffraction and thermogravimetric measurements. The investigation showed that the ZnOH groups appeared to be a desirable feature for the solid‐state synthesis of ZnO NCs that significantly decreased the decomposition temperature of crystalline precursors 3–5.
Graphene Oxide Nanoribbons: Improved Synthesis and Application in MALDI Mass Spectrometry
Authors: Liu Qian , Cheng Mengting , Wang Jing , Jiang Guibin 
Published: February 2015

AbstractGraphene nanoribbon is a novel variety of graphene with high length‐to‐width ratio and straight edges. Herein, we report an improved method for the synthesis of graphene oxide nanoribbons (GONRs) from longitudinal unraveling of multiwalled carbon nanotubes by means of a one‐step, one‐pot pressurized oxidation reaction. The obtained GONRs were characterized by different techniques. Furthermore, owing to their unique properties such as strong optical absorption and good water dispersibility, we show that GONRs can be used as an excellent matrix or probe in matrix‐assisted or surface‐enhanced laser desorption/ionization mass spectrometry (MALDI or SELDI MS) for the first time. In MALDI MS, GONRs generated significantly higher signals than conventional organic matrix and other graphene‐based matrices in the detection of low‐mass compounds. We also demonstrate the use of GONRs as a sensitive SELDI probe for simultaneous detection of multiple small molecules and profiling of small molecules in complex environmental samples, thus revealing its application potential in rapid screening of low‐mass pollutants in complex media.
