Divergent isoindolinone synthesis through palladium-catalyzed isocyanide bridging C–H activation
Cell Reports Physical Science, 2022 Summary: The formation of thermodynamically accessible metallacycle is crucial to achieve site-selective C–H bond activation. Here, we report an isocyanide-bridging C–H activation through the formation of a five-membered palladacycle. As such, a proximal
