Microwave-assisted continuous-flow reactions have attracted significant interest from synthetic organic chemists, especially process chemists from practical points of view, due to a less complicated shift to large-scale synthesis based on simple and continuous access to products with low energy requirements. In this personal account, we focused on the Suzuki-Miyaura and Mizoroki-Heck reactions, both of which are significantly important cross-coupling reactions for the synthesis of various functional materials. Microwave power is effective for heating. Typical homogeneous palladium catalysts, such as PdCl2 (PPh3 )2 , Pd(PPh3 )4 , and Pd(OAc)2 , as well as heterogeneous palladium catalysts, such as Pd-film, Pd/Al2 O3 , Pd/SiO2 , and Pd supported on polymers, can be used for these reactions.
