Plasmon enabled Claisen rearrangement with sunlight

Abstract

Plasmonic-heat generated from the solar irradiation of gold nanoparticles is used as the thermal energy source for the Claisen rearrangement of allyl phenyl ether to 2-allylphenol, which is conventionally performed...

Recent Applications of Photothermal Conversion in Organic Synthesis

“…This presents a potential challenge for organic reactions which are typically run dilute or require certain low-boiling solvents to work, as contact with the nanoparticle and effective heat transfer may become difficult. However, the Pillai group demonstrated that photothermal agents could function in a system without direct interaction between nanoparticle and substrate (Figure a) . Their 2023 report used a specialty reactor that isolated plasmonic gold nanoparticles from allyl phenyl ether to exempt any competitive plasmonic effects in their system.…”

“…However, the Pillai group demonstrated that photothermal agents could function in a system without direct interaction between nanoparticle and substrate (Figure 10a). 57 Their 2023 report used a specialty reactor that isolated plasmonic gold nanoparticles from allyl phenyl ether to exempt any competitive plasmonic effects in their system. Using this reactor and focused sunlight, they achieved a highly efficient Claisen rearrangement.…”
