Photocatalytic Generation of N-Centered Sulfamidyl Radical for Selective Functionalization of Si-H/Ge-H Bond
We have demonstrated that both sterically and electronically tunable sulfonamides can function as hydrogen atom transfer (HAT) catalyst for the selective activation of Si−H bond over C−H bonds of hydrosilane in the hydrosilylation of electron-deficient alkenes with the cooperation of organophotocatalyst.
Notably, this protocol can also be extended towards the selective abstraction of Ge−H bonds of hydrogermanes in the hydrogermylation.

Latency for all: Enabling Latency of Hoveyda-Grubbs Second Generation Catalysts by Adding Phosphite Ligands (How to put Hoveyda to sleep with phosphites)
Our groups research is focused on latent organometallic pre-catalysts. We can apply a form of stimuli (heat or light) to activate these dormant pre-catalysts to do olefin metathesis reactions. The scope of reactions is wide, and in particular in my research I'm interested in ring opening metathesis polymerization reactions. The complexes I developed contain big phosphite ligands that induce a specific configuration on the structure, helping us get the desired latent effect. We can take advantage of our latent complexes to create monomer-catalyst formulation to apply in 3D printing. Furthermore, in the search to develop new efficient complexes we discovered a unique synthetic technique in solidified solutions.
Our main scientific interest are the reaction mechanisms of various chemical transformations and their study by different experimental and theoretical techniques. A key area are directed transition metal-assisted C-H functionalizations. Nowadays, we focus on the factors responsible for the site selectivity of these reactions and ways to easily switch the selectivity by the factors like catalyst structure, acidity, irradiation and others. This is beneficial namely for the late stage functionalization approach.

One year later, he was awarded a DAAD scholarship to carry out his Ph.D. studies in Germany joining the group of Prof. Dr. P. Langer at University of Rostock. After he obtained his Ph.D. (2013), he moved to the Leibniz Institute für Katalyse (LIKAT) as a postdoctoral fellow, working under the guidance of Prof. Dr. A. Börner and Prof. Dr. M. Beller (2012−2014). In 2014, he returned to Chile and joined the Faculty of Science of University of Chile, where is currently Associate Professor. In 2021, he spent a short-term research stay (funded by the DAAD) at the Georg-August-Universität Göttingen in the group of Prof. Dr. L. Ackermann. His research interests include sustainable chemistry, its application to heterocycle synthesis, and (Photo)C−H functionalization reactions.
Yifei Zhou is a PhD in the laboratory of Organic Chemistry at Wageningen University, the Netherlands. His current research interests focus on Ruthenium-based organometallic chemistry and catalysis. He has an education background in material science and organic chemistry in his Bachelor and Master, respectively.
"We here demonstrate how crucial can be considered the chemical information contained in waste materials such as wool and how the composition of the biomass use is directly related to its applications in Chemistry and Catalysis"

Sardinian wool powder enables a sustainable hydroformylation in water
Zurzolo Simone, I obtained the master’s degree in 2023 with a grade of 110/110 cum laude and with honors; I obtained the qualification to the profession of Chemist in 2023. Winner of two research grants, the first "Development of an orphan drug for alkptonuria" at the University of Siena, Tutor Prof. Petricci Elena, the second "Development of molecules selective for "GLI" in the treatment of basal cell carcinoma and melanoma" at the same University of Siena Tutor Prof. Taddei Maurizio. In November 2023 I started my PhD, National PhD in Catalysis, at the University of Siena, title of the project "Solid industrial and agricultural waste for sustainable catalytic processes". I work mostly on the development of a sustainable method for the regioselective hydroformylation (HF) mediated by micronized Sardinian Sheep White Wool, on sustainable Rh/Fe/Mn/Pd catalyzed HF, Hydroamminomethylation, Carbonylation and Cyanation of aromatic bromides and multi-step synthesis of bioactive molecules.
Dr. Parameswaram Ganji received his Ph.D degree in the Department of Chemistry, Andhra University, India/CSIR-Indian Institute of Chemical Technology, India. After his PhD, he was awarded a prestigious National Postdoctoral Fellowship (N-PDF) sponsored by the Science and Engineering Research Board (SERB), DST, Government of India. After, he joined as a Research Assistant Professor at the National Institute of Chemistry (NIC) in Ljubljana, Slovenia. He is currently working as a Research Assistant Professor at Department of Surface Engineering (F4) at the Jožef Stefan Institute in Ljubljana, Slovenia. His research work is focused on heterogeneous catalysis, biodiesel and biomass conversion to green fuels, photocatalysis and electrocatalytic materials for CO2 reduction to methanol, etc.
"We designed a specific domino precursor with two alkyne units (with substituents that avoid β-hydride elimination) that led to two formal anti-carbopalladations followed by Suzuki or Sonogashira cross-coupling reaction intermolecularly as terminating step to afford an oligocyclic ring system."

From small peptides and amide macrocyclic rings to pharmacophores: photocatalysis in hoffman-löffler-freytag radical rearrangements
Assistant professor Davor Sakic is a junior group leader and head of LIGHT-N-RING installation grant awarded by Croatian Science Foundation. His research interest is in modelling reaction mechanisms of radical rearrangement, while his collaborators are experts in synthesis, radical stabilities, NMR, EPR, and laser flash photolysis.
