The first experimental evidence for the palladium-catalyzed secondary bond activation of allylic alcohols in a Tsuji-Trost reaction was provided by NMR methods, such as variable-temperature H NMR, diffusion-ordered spectroscopy (DOSY), Job's method, H NMR titration, and nuclear Overhauser enhancement spectroscopy (NOESY). The experimental results revealed that the substrate self-assisted activation of allylic alcohols is probably performed via a 1:1 binding six-membered-ring complex, which are formed by the formation of the secondary bonds, the hydrogen bond and P···O noncovalent bond between allylic alcohol and phosphonium ylide.

Substrate Self-Assisted Secondary Bond Activation of Allylic Alcohol in a Tsuji-Trost Reaction Revealed by NMR Methods.

In this paper, CuCoO dandelion arrays grown on nickel foam (CuCoO/NF) was successfully synthesized by a simple hydrothermal route with post-heat-treatment for emolying as a high-performance positive electrode material for hybrid supercapacitors. Due to the unique tree-dimension porous (3D) microstructure and binder-free electrode architecture, the CuCoO/NF electrode deliveries a large specific capacitance of 2656.7 F g at an areal current density of 1 mA cm. Moreover, it has an outstanding rate performance, as well as striking cycling stability. Additionally, a hybrid supercapacitors (HSCs) was fabricated using CuCoO as positive electrode and corals-like N-doping porous carbon (N-CCs) as negative electrode. The device exhibited a broad potential window of 1.55 V and a high specific capacitance of 273.9 F g, which result in a largest energy density of 91.4 Wh kg and a maximum power density of 13.4 kW kg. Finally, the assembled device manifests a preeminent electrochemical stability which maintained a 92.32% capacitance retention after 5000 cycles. The practical application was visually validated by lighting a blue light-emitting diode.
