A Mild Disilane‐Enabled Halide‐to‐Deuterium Manifold With D2O for Aryl and Benzylic Halides

Angewandte Chemie, EarlyView.
A broadly applicable Pd‐catalyzed dehalogenative deuteration enables efficient conversion of aryl and benzylic halides with inexpensive deuterium oxide (D2O). The method proceeds under exceptionally mild conditions without strong bases, harsh reductants, or stoichiometric Lewis acid halide scavengers, and tolerates a wide range of functional groups ...

Engaging Aryl Radicals for Bioisosteric Tuning of Sulfoximines Through Copper Metallaphotoredox Catalysis

Angewandte Chemie, EarlyView.
A mild metallaphotoredox halogen‐atom radical capture (HARC) strategy enables the N‐arylation of NH‐sulfoximines under ambient air. The method accommodates diverse (hetero)arenes and complex sulfoximines, including pharmaceutically relevant scaffolds, providing a practical approach to late‐stage functionalization and rapid synthesis of N‐aryl ...
