Sc(III) Complexes of Pyclen Derivative Ligands as Probes for Hypoxia: Synthesis, Chemical Characterization, 44Sc‐Radiolabeling, and Preclinical Assessment

open access: yesChemistry – A European Journal, EarlyView.
Hypoxia‐sensitive nitroimidazole‐functionalized pyclen derivatives were successfully synthesized and radiolabeled with 44Sc(III), affording stable and inert scandium complexes. Remarkable Sc(III)‐binding capabilities of the PC2A‐mono(amide) platform enabled excellent radiolabeling performance, with ≥92–99% yields and ≥99% radiochemical purity. MicroPET

One‐pot Base‐free Suzuki‐Miyaura [11C]Methylation: Kinetic and Mechanistic Insights

open access: yesChemistry – A European Journal, EarlyView.
A base‐free Suzuki–Miyaura [11C]methylation is achieved in a one‐pot process with [11C]CH3I on moderate yields. Electronic effects enable transmetallation without boronate activation, while kinetics and DFT show oxidative addition (heterolytic) as the rate‐limiting step.

Utilization of Waste Materials Using the Müller–Kühne Process—A Life Cycle Inventory Study

open access: yesChemie Ingenieur Technik, EarlyView.
This study presents a Life Cycle Inventory of the Müller–Kühne process (MKP), which converts gypsum waste into sulfuric acid and cement clinker. The MKP outperforms conventional cement production regarding material yield, though its specific energy demand is higher. Consequently, potentials for circular gypsum waste utilization are discussed.
