A dual-functional catalyst for selective dicarbamate synthesis via oxidative carbonylation: enhanced methoxylation for suppressing urea polymer formation

High-yield dicarbamate synthesis via oxidative carbonylation has been challenging due to substantial urea polymer formation. A Pd/CeO 2 catalyst was successfully synthesized dicarbamates while suppressing urea polymer formation. The superior methoxylation reactivity of Pd/CeO 2 , which originated fr...

Description
Summary:High-yield dicarbamate synthesis via oxidative carbonylation has been challenging due to substantial urea polymer formation. A Pd/CeO 2 catalyst was successfully synthesized dicarbamates while suppressing urea polymer formation. The superior methoxylation reactivity of Pd/CeO 2 , which originated from Pd–CeO 2 synergism, facilitated the conversion of the urea species, thereby preventing urea accumulation.
