Combined experimental and computational investigations of rhodium- and ruthenium-catalyzed C-H functionalization of pyrazoles with alkynes

Detailed experimental and computational studies are reported on the mechanism of the coupling of alkynes with 3-arylpyrazoles at [Rh(MeCN) 3Cp*][PF6]2 and [RuCl2(p- cymene)]2 catalysts. Density functi

Rhodium(III)-catalyzed oxidative coupling of 5-Aryl-1 H -pyrazoles with alkynes and acrylates

[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.
