Crystalline, room-temperature stable phosphine–SO2 adducts: generation of sulfur monoxide from sulfur dioxide

03.07.2018 | Florenz Buß; Philipp Rotering; Christian Mück-Lichtenfeld; Fabian Dielmann, Dalton Transactions, 2018

The particularly basic phosphines 1a–c readily form isolable, zwitterionic Lewis base adducts with SO2 that were fully characterized including by X-ray diffraction studies. Computational and reactivity studies show that these adducts readily release SO at room temperature driven by the formation ...

Cost-effective promoter-doped Cu-based bimetallic catalysts for the selective hydrogenation of C2H2 to C2H4: the effect of the promoter on selectivity and activity

03.07.2018 | Riguang Zhang; Bo Zhao; Leilei He; Anjie Wang; Baojun Wang, Physical Chemistry Chemical Physics, 2018

In order to probe into the effect of the promoter on the selectivity and activity towards C2H4 formation in the selective hydrogenation of C2H2 over cost-effective Cu-based bimetallic catalysts, different metal promoter M-modified Cu catalysts including Ni, Ag, Au, Pt, Pd and Rh have been ...

Elucidating Mysteries of Phase-Segregated Membranes: Mobile-Lipid Recruitment Facilitates Pores’ Passage to the Fluid Phase

03.07.2018 | Jesús María López Martí; Niall J English; Mario G Del Popolo, Physical Chemistry Chemical Physics, 2018

Phase segregation of multicomponent lipid bilayers leads to, under phase-coexistence conditions, domain formation, featuring delimitation by essentially one-dimensional borders. (Micro-)phase segregation of bilayers is proposed to influence the physiological behaviour of cell membranes and ...

Carbonaceous two-dimensional lattice with FeN4 units

03.07.2018 | Jun Maruyama; Taiji Amano; Satoshi Inoue; Yasuji Muramatsu; Noriko Yoshizawa; Eric Gullikson, Chemical Communication, 2018

Metal-containing carbonaceous two-dimensional lattice was formed on a graphene plane by sublimation, deposition, and pyrolysis of Fe phthalocyanine (Pc). The formation and growth of the FePc-derived -conjugated planar system were reflected by its orientaitonal conversion from the perpendicular ...

Carbenium ion formation by fragmentation of electrochemically generated oxonium ions

03.07.2018 | Anna Lielpetere; Aigars Jirgensons, Organic & Biomolecular Chemistry, 2018

Fragmentation of electrochemically generated oxonium ions can be exploited to form carbenium ions at low oxidation potential in the presence of a nuclephile. The application of this concept is demonstrated for allylation of carbenium ions generated by anodic oxidation of ...

Redox Behaviour of ([fc(NPiPr2)2]Fe)2, Formation of an Iron-Iron Bond and Cleavage of Azobenzene

03.07.2018 | Faser Pick; Daniel B Leznoff; Michael D Fryzuk, Dalton Transactions, 2018

The redox behaviour of the dimeric tetrairon complex, ([fc(NPiPr2)2]Fe)2 (where fc(NPiPr2)2 = 1,1’-(C5H4NPiPr2)2Fe) has been investigated. Upon reduction with KC8 a Fe-Fe bond is formed with the complex maintaining a high spin configuration and having the formula [K(THF)6]([fc(NPiPr2)2]Fe)2. In ...

Nature-Inspired Catalyst for Visible-Light-Driven Photocatalytic CO2 Reduction

03.07.2018 | Zhifeng Jiang; Hongli Sun; Tianqi Wang; Bo Wang; Wei Wei; Huaming Li; Shouqi Yuan; Taicheng An; Huijun Zhao; Jiaguo ..., Energy & Environmental Science, 2018

We demonstrate a rational fabrication of hierarchical treated rape pollen (TRP), a biological material as metal-free catalyst for visible-light-driven photocatalytic CO2 reduction. The TRP catalyst exhibits excellent visible-light-driven carbon monoxide (CO) formation activity of 488.4 μmol h-1 ...
