It's a Gas: Bioconjugation With Vapor‐Phase Reagents

open access: yesChemistry – A European Journal, EarlyView.
Gaseous reagents are an emerging class of bioconjugation reagents that can offer alternative selectivity paradigms for the construction of precise bioconjugates. A variety of both inert and highly reactive gases have recently been developed for bioconjugation use.

Dual Ligand‐Enabled Nondirected C─H Olefination of (Hetero)Arenes for the Synthesis of Clickable Derivatives

open access: yesChemistry – A European Journal, EarlyView.
We report an efficient method for late‐stage installation of “clickable” alkyne groups into diverse (hetero)arenes. Using a dual‐ligand palladium catalyst that combines an NASA ligand with an N‐heterocycle, an acrylate unit bearing a terminal alkyne can be introduced via nondirected C─H activation.

Oxidative degradation of aniline derived compounds over carbon based materials

open access: yes, 2010
The objectives of this work were: the preparation of different forms of carbon materials (AC, ACSA, CX, CXSA and GBCM), assessment of their catalytic efficiency in the CWPO of the azo dye Chromotrope 2R. Initially the materials were characterized by several techniques, afterwards adsorption and reaction runs were done and lastly the samples obtained ...

Enantioselectivity in Transition Metal Catalyzed Propargylic Substitution Reactions: A Theoretical Perspective

open access: yesChemistry – A European Journal, EarlyView.
Recent theoretical efforts to elucidate the origin of enantioselectivity in transition metal‐catalyzed propargylic substitution reactions are highlighted in this review. ABSTRACT In recent years, asymmetric catalytic propargylic substitution reactions have undergone remarkable development, enabling the construction of chiral carbon centers adjacent to ...

Insights into the Photocatalytic Arene Bromination Enabled by Cs2AgBiBr6 Microparticles

open access: yesChemistry – A European Journal, EarlyView.
A sustainable photocatalytic bromination of electron‐rich arenes is enabled by low‐toxicity Cs2AgBiBr6 double‐perovskite microparticles using HBr as an atom‐economical bromine source. Surface‐derived bromine radicals drive highly selective mono‐bromination under mild conditions.

Dihydroquinazolinones by Titanocene‐Catalyzed Reductive Radical Addition to Quinazolinones

open access: yesChemistry – A European Journal, EarlyView.
Tri‐ and tetracyclic dihydroquinazolinones or quinazolinones by titanocene catalysis: A highly diastereoselective and efficient reductive radical addition to quinazolinones enables an unprecedented entry to pharmaceutically relevant dihydroquinazolinones by avoiding the interception of radical intermediates prior to the slow radical addition.
