ABSTRACT The overuse of synthetic pesticides in agriculture has raised significant environmental and health concerns. Biopesticides have emerged as viable, environmentally compatible alternatives. However, recent comprehensive reviews integrating all biopesticide categories and emphasizing their contribution to synthetic‐pesticide‐free and health‐safe ...

Expanding the Chemical Space of 1,2-Difunctionalized Cyclobutanes
An efficient approach to the synthesis of previously unavailable or hardly accessible 1,2-difunctionalized cyclobutanes (mostly with NH2/NHBoc, OH, SH, or SO2F groups attached to the carbocycle either directly or via a CH2 unit) relying on the divergent ...

Self‐nanostructuring of redox‐active organic small molecules through in situ electrochemical postcrosslinking enabled an aqueous‐processed, stable, fast‐rechargeable organic electrode even with a high active content ratio and mass loading. ABSTRACT Redox‐active organic materials (ROMs) for batteries are emerging as sustainable alternatives to inorganic

This research introduces an ortho‐palladated oxazolone moiety that can undergo rapid and reversible photocycloaddition by low‐intensity green light irradiation. Integration of such a photoresponsive function into crosslinked polymer structures enables rapid photo‐ and thermo‐switching of polymer properties, presenting a unique light‐directed covalent ...

Synthesis of Cyclobutanes Utilizing Green Chemistry
The reactions of cyclobutanes is a topic that has yet to be thoroughly studied due to the challenges of working with the strained molecule. Cyclobutanes have been used as synthetic analogs for several different amino acids and biomolecules because of ...

Cycloaddition and Annulation Reactions with Donor‐Acceptor Cyclobutanes
Donor‐acceptor (DA) cyclobutanes are emerging as valuable synthetic intermediates due to their ring strain and polarized C─C bonds, which allow for 1,4‐dipolar reactions.

A Practical Catalytic Method for Preparing Highly Substituted Cyclobutanes and Cyclobutenes
Tf2NH, an organic acid, efficiently catalyzes (2 + 2) cycloaddition reactions of silyl enol ethers with acrylates or propiolate. The process affords highly substituted cyclobutanes in high yield with high stereoselectivity under practical and ...

1,3-Difunctionalization of [1.1.1]propellane through iron-hydride catalyzed hydropyridylation
Current methodologies for the functionalization of [1.1.1]propellane primarily focus on achieving 1, 3-difunctionalized bicyclo[1.1.1]pentane or ring-opened cyclobutane moiety. Herein, we report an innovative approach for the 1, 3-difunctionalization of [
