[2+2]-cycloadditions of alkenes with the triphenylallenyl cation [PDF]
, 1984 The triphenylallenyl cation (8), generated from triphenylpropynol (7) and FSO3H, reacts with alkenes to give the allyl cations 12, which may be deprotonated to yield the methyleneccylobutenes 14.

Conjugated Inorganic–Organic Hybrid Polymers with p‐Block Elements
Angewandte Chemie International Edition, Volume 65, Issue 2, 9 January 2026.The influence of various p‐block element motifs on the photophysical properties of conjugated inorganic‐organic hybrid polymers is surveyed regarding applications in organic electronics. Recent advances in the use of heavier elements as well as heavier multiple bonds and the development of diverse (post‐)functionalization strategies suggest ample scope

Tracking Propagating Perturbations in Chemical Reactions
ChemistryEurope, Volume 4, Issue 1, January 2026.Tracking the propagation of periodic concentration perturbations within chemical reactions is presented as a powerful strategy for probing reaction connectivity and the kinetics of individual reaction steps. This approach is demonstrated here for the organocatalytic Michael‐type addition of cyclopentadiene to α,β‐unsaturated aldehydes, based on ...

The alpha-effect in cyclic secondary amines: new scaffolds for iminium ion accelerated transformations [PDF]
, 2009 Five-membered secondary amine heterocycles containing an α-heteroatom were prepared and shown to be ineffective as catalysts for the iminium ion catalysed Diels–Alder reaction between cinnamaldehyde and cyclopentadiene.

Carbon Neutralization, Volume 5, Issue 1, January 2026.In this work, we constructed homomeric high‐density FLPs. By establishing a descriptor model and a novel strategy for dynamic time alignment analysis, we accelerated transition state search by 220‐fold, pioneering a “dynamic dimension” for catalytic performance.
