A high-capacity, high-power organic electrode supercritical CO impregnation into activated carbon micropores.

Herein, we report the impregnation of chloranil into activated carbon micropores using scCO. The sample prepared under 105 °C and 15 MPa showed a specific capacity of 81 mAh g, except for the electric double layer capacity at 1 A g. Additionally, approximately 90% of the capacity was retained even at 4 A g.

N-formyl-stabilizing quasi-catalytic species afford rapid and selective solvent-free amination of biomass-derived feedstocks.

Nitrogen-containing compounds, especially primary amines, are vital building blocks in nature and industry. Herein, a protocol is developed that shows in situ formed N-formyl quasi-catalytic species afford highly selective synthesis of formamides or amines with controllable levels from a variety of aldehyde- and ketone-derived platform chemical substrates under solvent-free conditions. Up to 99% yields of mono-substituted formamides are obtained in 3 min.
