DOI: 10.1002/ejoc.201601247
Abstract: A density functional theory study is performed on the reactions of α,β-unsaturated oxime pivalates and alkenes through Cp*RhIII-catalyzed (Cp* = pentamethylcyclopentadienyl) C–H activation. The catalytic cycle involves reversible metalation–deprotonation, migratory alkene insertion, pivaloyl transfer to… read more here.

Abstract: In spite of their widespread use as catalysts, 1,2,3,4,5-pentamethylcyclopentadienyl (Cp*) iridium complexes have been rarely employed in the synthesis of pyridine derivatives. Herein, we used density functional theory (DFT) calculations to predict the [Cp*Ir(OAc)]+-catalysed synthesis… read more here.

DOI: 10.1039/d2ra03875g
Abstract: An efficient method for the synthesis of multi-substituted pyridines from β-aryl-substituted α,β-unsaturated oxime ethers and alkenes via Pd-catalyzed C–H activation has been developed. The method, using Pd(OAc)2 and a sterically hindered pyridine ligand, provides access… read more here.
