Cationic ruthenium(II) complexes allowed for highly efficient oxidative annulations of aryl- and alkyl-substituted alkynes by 5-aryl-1H-pyrazoles. The C-H/N-H bond functionalization strategy furthermore proved applicable to the high-yielding activation of

[RhCp Cl2]2-catalyzed oxidative coupling of 5-aryl-1H-pyrazoles with alkynes and acrylates has been achieved using Cu(OAc)2 as an oxidant. Coupling with alkynes afforded six-membered azacycles as a result of C-C and C-N coupling. Coupling with acrylates followed a process of diolefination and a subsequent aza-Michael cyclization.
