Transition metal catalyzed C-H bond activation has become one of the most important tools for constructing new chemical bonds. Introducing directing groups to substrates is key a successful reaction, these can also be further transformed in reaction. Amidines with their unique structure and reactivity are ideal transition metal-catalyzed transformations. This review describes major advances mechanistic investigations activation/annulation tandem reactions amidines until early 2024, focusing on unsaturated compounds, such as alkynes, ketone, vinylene carbonate, cyclopropanols derivatives. Meanwhile this manuscript explores reaction different carbene precursors, example diazo azide, triazoles, pyriodotriazoles, sulfoxonium ylides well own activation/cyclization reactions. A bright outlook provided at end manuscript.
