C1 chemistry plays a vital role in the chemical and energy industry in terms of recycling C1 molecules andhigh productivity. As one of the C1 chemistry reactions, oxidative carbonylation of alcohols to correspondingdialkyl carbonates (DACs) has been studied but still has problems with catalysts in terms of corrosionand low yield of DACs. To address this issue, various Se/Ph2Se2/tertiary amine catalytic systemswere applied to the oxidative carbonylation of alcohols to produce DACs, and Se/Ph2Se2/DMAP showedhigher catalytic activity [60.9% yield of bis(2-methoxyethyl) carbonate (BMEC) at a turnover frequency(TOF) value = 32.5 h1] compared to other tertiary amines (TAs) systems in the oxidative carbonylationof 2-methoxyethanol (MEG). Moreover, with this catalytic system, the oxidative carbonylation of C1–C4n-alcohols yielded over 40% of DACs with high TOF value (over 40 h1), which are unprecedentedcatalytic activity in terms of both yield and TOF value, compared with previous reports. We also founda relationship between the hydrogen bond (HB) strength of alcoholTA and the catalytic performances. Additionally, the catalytic activity with pKa of TA showed volcano-type correlation. Finally, weinvestigated the role of TA and proposed a plausible mechanism based on 1H NMR study and theaforementioned correlations.
