Pd‐Promoted General Synthesis of Aurones Using CO2

The carbonylation of alkynes using CO2 to generate aurones is unknown. Here, we report palladium-catalyzed carbonylation of terminal aromatic alkynes and the waste hydrosilane, poly(methylhydrosiloxane) (PMHS) with 2-iodophenol using CO2 to produce aurones. A variety of terminal alkynes and the substituted 2-iodophenols are transformed into aurones...

Spreading the Landscape of Dual Ion Batteries: from Electrode to Electrolyte

The Front Cover shows the working mechanism of dual-ion batteries (DIBs). That is, the positive ions in the electrolyte move and embed into the anode during charging, while the negative ions in the electrolyte move and embed into the cathode, whereas it is the processes are reversed for the discharging process. Such a battery has two types of ions that...
