Application

• Depolymerization of poly (bisphenol A carbonate) under mild conditions by solvent-free alcoholysis catalyzed by 1, 8-diazabicyclo undec-7-ene as a recyclable: DBU catalyzes the depolymerization of polycarbonates under mild, solvent-free conditions, demonstrating its effectiveness and recyclability as a catalyst (E Quaranta, D Sgherza, G Tartaro, 2017).
• Activating cellulose via its reversible reaction with CO2 in the presence of 1, 8-diazabicyclo undec-7-ene for the efficient synthesis of cellulose acetate: This research shows how DBU can activate cellulose for a reversible reaction with CO2, facilitating the synthesis of cellulose acetate (Y Yang, L Song, C Peng, E Liu, H Xie, 2015).
• Bifunctional 1, 8-Diazabicyclo undec-7-ene for Visible Light-Induced Heck-Type Perfluoroalkylation of Alkenes: DBU acts as a bifunctional organocatalyst for visible light-induced Heck-type perfluoroalkylation of alkenes, showcasing its potential in photoredox catalysis (L Tang, G Lv, Y Fu, XP Chang, R Cheng, 2022).
• Cooperative calcium-based catalysis with 1, 8-diazabicyclo undec-7-ene for the cycloaddition of epoxides with CO2 at atmospheric pressure: This study demonstrates the cooperative catalysis of CaBr2 and DBU in the cycloaddition of epoxides with CO2, highlighting a sustainable approach to carbonate synthesis (X Liu, S Zhang, QW Song, XF Liu, R Ma, LN He, 2016).
