The Genuine Carbene Conundrum

open access: yesChemistry – A European Journal, EarlyView.
From fleeting intermediates to well‐defined molecular structures, carbenes (neutral divalent carbon) remind us that the most reactive ideas often make a large impact. Despite their wide‐ranging applications, the direct characterization of these reactive species remains a persistent experimental challenge.

Fluorohydration of alkynes via I(I)/I(III) catalysis

open access: yesBeilstein Journal of Organic Chemistry, 2020
Substrate specificity is ubiquitous in biological catalysis, but less pervasive in the realm of small-molecule catalysis. Herein, we disclose an intriguing example of substrate specificity that was observed whilst exploring catalysis-based routes to ...

The Dihydroindeno[2,1‐c]fluorene Core: from Syntheses to Properties and Potential Applications

open access: yesEuropean Journal of Organic Chemistry, Accepted Article.
In the last decade, substances possessing the dihydroindeno[2,1‐c]fluorene scaffold showed interesting photo‐physical properties and other potential applications in electronics. The afore‐mentioned compounds belong to the family of five regioisomeric dihydroindenofluorenes, but unlike other ones, they possess angular or, in the case of higher congeners,

Substrate Preorganization Within Photoactive Pt12L24 Nanospheres for Accelerated Decarboxylation Catalysis at Low Concentrations

open access: yesAngewandte Chemie, Volume 137, Issue 31, July 28, 2025.
Substrate preorganization is used to overcome the concentration and lifetime constraints of photoredox catalysis. Pt12L24 nanospheres equipped with guanidinium moieties (LGua) are able to preorganize carboxylic acids and act as photocatalysts for the decarboxylative oxygenation reaction.
