Over the past few decades, transition metal-catalyzed synthetic transformations have gained profound importance as it proves to be a powerful strategy to enable C–C and C–heteroatom bond formation in a highly atom- and step-economical manner. In recent years, transition-metal-catalyzed C−H bond activation has come out as a most straightforward and powerful tool. The success of transition-metal-catalyzed C–H activation for the formation of new C-C bonds has anticipated synthetic chemists to develop double C–H activation protocol. This protocol enables the formation of multiple bonds in one pot, making it more atom- and step-economical compared to available methods. In the literature, oxidative coupling via dual C-H activation for arylation is well explored.[1] However, use of pi-components such as alkynes, alkenes as a coupling partner using this protocol are still unexplored. Recently, oxidative coupling between arene and olefines via 2-fold C-H activation evolving as an important and fascinating research topic to build a cyclic complex organic moiety effortlessly.[2]
In this research proposal seminar, the literature background of palladium-catalyzed dual CH activation followed by functionalization will be discussed along with future perspective on the Pd-catalyzed [3+2] annulation with alkenes through dual CH activation.[3]
