Cobalt-catalyzed directed C–H alkenylation of pivalophenone N–H imine with alkenyl phosphates
Beilstein Journal of Organic Chemistry, 2018 A cobalt–N-heterocyclic carbene (NHC) catalyst efficiently promotes an ortho C–H alkenylation reaction of pivalophenone N–H imine with an alkenyl phosphate. The reaction tolerates various substituted pivalophenone N–H imines as well as cyclic and acyclic

C–H Activation via Group 8–10 Pincer Complexes: A Mechanistic Approach
InorganicsC–H bond activation is a crucial synthetic strategy widely utilized in both academic and industrial settings. Due to the strong and kinetically inert nature of the C–H bond, its functionalization typically requires metal-based catalysts.
