Ligand‐Controlled Chemoselectivity in the Rhodium‐Catalyzed Synthesis of Pentafulvenes via (2 + 2 + 1) Alkyne Cyclotrimerization

Angewandte Chemie, EarlyView.
Chemoselectivity Challenge: A precise catalyst design allows for chemoselectivity control over alkyne reactivity to yield pentafulvenes via (2 + 2 + 1) cyclotrimerization. Operative mechanism has been elucidated by means of stoichiometric and deuteration experiments, as well as DFT calculations.

Historia, análisis de los Centros Rurales de Innovación Educativa y propuesta didáctica

Los Centros Rurales de Innovación Educativa (CRIE) son un gran apoyo y forman un binomio muy importante junto a los Colegios Rurales Agrupados (CRA) y aquellos centros educativos incompletos que, debido a su localización, falta de recursos y bajos ratios de alumnos en los centros, permiten fomentar la socialización entre iguales, crear vínculos entre ...

An Atomically Dispersed Photocatalyst for Undirected para‐Selective C─H Bond Functionalizations

Angewandte Chemie, EarlyView.
This study presents an atomically dispersed recyclable heterogeneous photocatalytic method for para‐selective trifluoromethylation of electron‐deficient arenes without directing groups. Unlike previous substrate‐dependent approaches, this recyclable, atomically dispersed photocatalyst enables scalable synthesis of bioactive trifluoromethylated ...

Tailoring Tubular Supramolecular Polymers with Polar Lumens to Host Hydrophilic Dye Molecules

Angewandte Chemie, EarlyView.
A unique class of tubular polymer structures that are soluble in apolar organic solvents but are endowed with polar pores has been created through the rational design of the monomer units, which self‐assemble in amphiphilic cyclic entities that then stack into tubular architectures. These tailored assemblies are able to selectively host hydrophilic dye
