Surface Lewis basic site enabled proton abstraction for the regioselective synthesis of ynones and flavones over the Pd0/Cs-ZSM-5 catalyst: mechanistic understanding and structure–activity correlation

Abstract

An environmentally benign and highly regioselective catalyst that possesses strong Lewis basicity demonstrated high rates of ynones and flavones under mild reaction conditions in the absence of a base, ligand, and co-catalyst.
