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.

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.
