The concept of strain in organic compounds is as old as modern organic chemistry and was
initially introduced to justify the synthetic setbacks along the synthesis of small ring systems …

Visible‐light photocatalysis is a rapidly developing and powerful strategy to initiate organic
transformations, as it closely adheres to the tenants of green and sustainable chemistry …

We report the use of photocatalysis for the homolytic ring-opening of carbonyl
cyclopropanes. In contrast to previous studies, our approach does not require a metal …

Due to their inherent ring strain, three-membered carbocyclic-and heterocyclic ring
structures are versatile synthetic building blocks. Traditional ring-opening methods of these …

Cyclometalated Ir (III) complexes are often chosen as catalysts for challenging photoredox
and triplet–triplet-energy-transfer (TTET) catalyzed reactions, and they are of interest for …

We describe a synergistic utilization of cerium photocatalysis and photoinduced electron
transfer catalysis that enables an atom-and step-economical ring expansion of readily …

In the last years, an increasing interest towards the development of novel enantioselective
strategies in photocatalysis has been observed within the research community. The high …

The dual channels ion imprinted POPD-CoFe 2 O 4 heterojunction photocatalyst (magnetic
ion imprinted heterojunction photocatalyst) was synthesized by utilizing the microwave …

The herein reported visible‐light‐activated catalytic asymmetric [3+ 2] photocycloadditions
between cyclopropanes and alkenes or alkynes provide access to chiral cyclopentanes and …

The importance of intramolecular constraints in cyclic transition-state geometries is
especially pronounced in n-endo-tet cyclizations, where the usual backside approach of a …
