Crystal Orientation Regulation and Dynamic Protection via Dual Interface Engineering for Dendrite‐Free Zinc Deposition

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A dual‐interface engineering strategy is innovatively proposed to achieve dendrite‐free Zn anodes through crystallographic orientation regulation and adaptive interfacial protection. By pre‐coating eco‐friendly di‐pentaerythritol, horizontal growth of ZHS along the (001) plane is induced, which in turn guides epitaxial Zn deposition on the (002) plane.

Visible‐Light‐Promoted, (Photo)catalyst‐Free Synthesis of 3‐Sulfonyl‐Azaspiro[4.5]trienones via Arylazo Sulfones

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A set of 3‐sulfonyl‐azaspiro[4.5]trienones have been obtained via a metal‐ and photocatalyst‐free visible‐light‐driven dearomative strategy. The protocol exploits arylazo sulfones, which act simultaneously as the light absorber and sulfonyl‐radical source, enabling ipso‐spirocyclization of differently substituted N‐aryl propiolamides.

Photochemical Decatungstate‐Catalyzed Hydroacylation of Maleimides

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A photocatalytic protocol to access substituted succinimides via tetra‐n‐butylammonium decatungstate photocatalysis is reported. This direct radical‐driven hydroacylation of a variety of N‐substituted maleimides shows tolerance to various aldehydes (or alkanes), affording differentially substituted succinimides in high yields. Succinimides constitute a

1,2,6‐Thiadiazin‐4‐ones: Robust Photocatalysts for the Green Aerobic Oxidation of Sulfides to Sulfoxides

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A new photocatalyst for the aerobic photochemical oxidation of sulfides to sulfoxides is described under really low catalyst loading (0.01 mol%) and methanol as the green solvent. The chemoselective oxidation of sulfides to sulfoxides is accomplished using a new family of photocatalysts, namely 1,2,6‐thiadiazin‐4‐ones. Utilizing a low catalyst loading (
