Surface Lewis Basic Site Enabled Proton Abstraction for the Regioselective Synthesis of Ynone and Flavone over Pd0/Cs-ZSM-5 Catalyst: Mechanistic Understanding and Structure-Activity Correlation

Regioselective nature of the Pd0/Cs-ZSM-5 catalyst was established by HCOOH-IR and CO chemisorption. Mechanistic studies revealed that CO was activated on the surface Pd(0), and the alkyne proton was abstracted...
