Outline of Final Research Achievements

In this research, I proposed a new photoinduced Suzuki-Miyauira coupling reaction by the formation of active electron rich Pd(0). A photoinduced Suzuki-Miyauira coupling reaction has been realized by molecule Pd(II) complex containing a Ru(II)-polypyridyl derivative as a visible light photosensitizing unit, where an electron and/or energy transfer from excited Ru species to Pd(II) may facilitate the formation of active electron rich Pd(0) and oxidative addition step with aryl halides.
Furthermore, the formation of bimetallic Pd/Au and Pd/Ag NPs exhibited specific photocatalytic activity in the Suzuki coupling reaction via localized surface plasmon resonance (LSPR)-assisted deposition under visible light irradiation.
