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: A RhIII-catalyzed C(sp2)-H N-heteroarylation and esterification cascade of aryl carboxylic acids with N-heteroaromatic boronates and 1,2-dichloroethane in a one-pot synthesis has been disclosed. The strong coordinating ability of ortho- and meta-substituted pyridine boronates and pyrazoles… read more here.
