Applications

It is reagent used forligand-free palladium-catalyzed Suzuki-Miyaura cross-couplings, ruthenium catalyzed direct arylation of benzylic sp3 carbons of acyclic amines, Diels-Alder or C-H activation reactions, regioselective Suzuki-Miyaura coupling and tandem palladium-catalyzed intramolecular aminocarbonylation and annulations, N-arylation of phenylurea using copper acetylacetonate catalyst, environmentally benign one-pot synthesis through a double arylation process, copper-mediated cyanation, copper-catalyzed arylations regioselective glycosylations. Suzuki couplings followed by arylations, X-ray absorption on rhodium-grafted hydrotalcite catalyst for heterogeneous 1,4-addition reaction of organoboron reagents to electron deficient olefins. It is used in Preparation of combretastatin analogs as potential antitumor agents and human immunodeficiency virus (HIV) protease inhibitors with antiviral activities against drug-resistant viruses
