4-(Dimethylamino)pyridine-Catalysed Iodolactonisation of [gamma],[small delta]-Unsaturated Carboxylic Acids

20.05.2015 | Chuisong Meng; Zhihui Liu; Yu-Xiu Liu; Quingmin Wang, Organic & Biomolecular Chemistry, 2015

4-(Dimethylamino)pyridine functioned as an excellent catalyst for iodolactonisation reactions of γ,δ-unsaturated carboxylic acids, affording γ-lactones, δ-lactones, or both under neutral conditions at room temperature. The effects of substrate structure on the iodolactonisation were investigated, ...

Deep Eutectic Solvents: biorenewable reaction media for Au(I)-catalysed cycloisomerisations and one-pot tandem cycloisomerisation/Diels-Alder reactions

20.05.2015 | Joaquin García-Álvarez; Vidal Cristian; Lukas Merz, Green Chemistry, 2015

Cycloisomerisation reactions of (Z)-enynols into furans can be conveniently performed, for the first time, in the eutectic mixture 1ChCl/2Gly as solvent and under standard bench conditions (at room temperature and under air) by using the new bis(iminophosphorane)-Au(I) complex ...

Scaling of Anomalous Hall Effects in Facing-Target Reactively Sputtered Fe4N Films

20.05.2015 | Yan Zhang; Wenbo Mi; Xiaocha Wang; Xixiang Zhang, Physical Chemistry Chemical Physics, 2015

Anomalous Hall effect (AHE) in the reactively sputtered epitaxial and polycrystalline γ′-Fe4N films is investigated systematically. The Hall resistivity is positive in the entire temperature range. The magnetization, carrier density and grain boundaries scattering have a major impact on the AHE ...

Room-temperature ferromagnetism in Co doped MoS2 sheets

20.05.2015 | ZhongCheng Xiang; Zhong Zhang; XiJin Xu; Qin Zhang; QingBao Wang; ChengWu Yuan, Physical Chemistry Chemical Physics, 2015

Via the hydrothermal method, we synthesized MoS2 nanosheets with varying Co dopant concentrations of 0%, 3%, 7%, using cobaltous acetate as a promoter, and marked as A, B, and C, respectively. We found that the thickness and flatness of the nanosheets increased with the increase of the co dopant ...
