Methyl on the Bridge: 2‐Methyl Propellane as Precursor for 1,3‐Substituted 2‐Methylated Bicyclo[1.1.1]Pentanes

Chemistry – A European Journal, EarlyView.
The synthesis of 2‐methyl propellane and its conversion to various 1,2‐ and 1,2,3‐di‐ and trisubstituted bicyclopentanes is reported. Abstract Bicyclo[1.1.1]pentanes (BCPs) have emerged as isosteric replacements for mono‐ and para‐substituted benzene rings in medicinal and materials applications, involving substitution at the BCP bridgehead (1,3 ...

Versatile Palladium‐Catalyzed C‐H Arylation of Fluoroarenes with 2‐Chloropyridine Derivatives

Chemistry – A European Journal, EarlyView.
Direct C─H arylation of fluoroarenes with 2‐chloropyridines is enabled by a simple Pd/SPhos system in isopropyl acetate. The method uses inexpensive reactants and shows broad scope and high yields. DFT computations explain reactivity and selectivity.

Synthesis and Isolation of Bismuth Scorpionate Complexes: Toward Bond Activation via Bismuth‐Ligand Cooperation

Chemistry – A European Journal, EarlyView.
ABSTRACT Over the past twenty years, main group chemistry has significantly expanded its scope to include reactivities once considered the exclusive domain of transition metals. Among the emerging concepts, element‐ligand cooperation has proven to be a powerful strategy for enabling bond activation reactions but remains relatively unexplored for ...

Modular Rh‐Catalyzed Synthesis and Biological Profiling of Diverse Pentafluorobenzenesulfonamide Reactive Fragments

Chemistry – A European Journal, EarlyView.
A modular Rh‐catalyzed synthetic approach enabled the preparation of diverse reactive fragments from available substrates. The reactive fragments modified Aurora A kinase via several distinct modification reaction classes. In a complex biological environment, the constellation of modified proteins depended critically on the reactive fragment structure.

Alkene Hydrogenation by a Cationic, Nine‐Coordinate Molybdenum(VI) Pentahydride Catalyst

Chemistry – A European Journal, EarlyView.
While late 3d metals dominate efforts to replace precious metals in homogeneous hydrogenation, molybdenum has remained largely ignored. This work reveals that a nine‐coordinate pentahydrido molybdenum complex can hydrogenate a broad range of alkenes efficiently, demonstrating that early‐metal polyhydrides can serve as genuine catalysts rather than mere
