Strategy for Synthesizing Novel Acetamidines as CO 2 -Triggered Switchable Surfactants via Acetimidates

Abstract

In this study, we developed a strategy for using the Scoggins procedure in the synthesis of acetamidines as novel CO 2 -triggered switchable surfactants via acetimidates by effectively tuning the chemical equilibrium. The as-synthesized N’-alkyl-N,N-diethylacetamidines exhibit excellent CO 2 /N 2 switchability and their bicarbonate salts have the ability to emulsify oil–water mixtures.
