Catalysis
Visible light-driven polymer and small molecule synthesis

New from the Miyake group: Phenoxazine- and dihydrophenazine -derived compounds were demonstrated in the application of photoredox-catalyzed atom transfer radical polymerization (ATRP) for controlled polymer synthesis and small molecule transformations such as trifluoromethylation and dual photoredox/nickel catalyzed C−N and C−S cross-couplings.
Palladium-catalyzed C−N cross-couplings
The Buchwald lab continues to produce discrete ligands and fourth-generation catalysts for improved reactivity, solubility, ease of activation, and minimization of side product formation. The newest include the EPhos ligand and EPhos Pd G4 precatalyst for palladium-catalyzed C−N cross-couplings between primary amines and aryl halides to form 2-arylaminooxazoles and 4-arylaminothiazoles.
REAGENTS

Access to saturated N-heterocycles
Our suite of SiLicon Amine Protocol (SLAP) Reagents developed by the Bode lab enables piperazine synthesis from aromatic, heteroaromatic, and aliphatic aldehydes and ketones by using an iridium photoredox catalyst. The SLAP Reagents provide a tin-free alternative to the popular SnAP Reagents for access to saturated N-heterocycles, including morpholines, piparazines, thiomorpholines, oxazepines, and diazepines.
