Alkoxyallenes in Modern Synthesis: Reactivity, Catalysis, and Complexity Generation
The last decade has witnessed a remarkable transformation in alkoxyallene chemistry. Although historically employed as synthetic equivalents of acrolein or as versatile 3C synthons, alkoxyallenes are now increasingly recognized as highly adaptable platforms for synthetic design.

We have developed a visible‐light‐driven, transition‐metal‐free protocol for the chemodivergent borocarbonylation of trifluoromethyl styrenes which integrates radical 1,2‐boron migration, CO trapping, and intermolecular C–C bond formation into a single multicomponent cascade.

Ni‐catalyzed cross‐electrophile coupling (XEC) of aryl iodides with benzyl chlorides proceeds efficiently in the deep eutectic solvent (DES) choline chloride/urea, replacing hazardous amide solvents. Under mild, aerobic, heterogeneous conditions, diarylmethanes form in up to 95% yield.

The polyfunctionality of Coptic Egyptian relative complementisers
The present study is concerned with the complex ways in which alternating relative complementisers in Coptic are employed as a morphological flagging device for unbounded dependencies in various types of relative clause constructions and wh questions.

Retro‐Hetero‐Michael Addition Strategies in Organic Synthesis
In this review, synthetic approaches to carbo‐ and heterocyclic compounds, including natural products, published in the last 15 years (2011–2025) which have either relied upon or included a retro‐hetero‐Michael addition step at any stage are discussed.

A robust and efficient method to access diversely functionalized fluorinated piperidines was developed. The approach features the hydrogenation of polysubstituted pyridines bearing CF3, CF2H, and CF2CO2Et substituents using an inexpensive, readily available heterogeneous Pd/C catalyst under air‐ and moisture‐tolerant conditions, offering an appealing ...
