Abstract
Abstract Various microwave-heated heterogeneous catalytic reactions can be accelerated by choice of the catalyst supports and solvents. In this work, heterogeneous Pd catalysts supported on ordered mesoporous carbon CMK-3 and related catalysts were prepared. In the presence of these catalysts, the effect of microwave heating on Pd-catalyzed Suzuki–Miyaura coupling as a probe reaction was investigated. The CMK-3 worked efficiently as a “carbon nanoflask” under microwave irradiation, especially in nonpolar solvents such as toluene and o-xylene with a lower ratio of dielectric constant (ε′) to dielectric loss (ε′′) (=tan δ).
