Harnessing Carbenoid Reactivity From Imidazoles and Oxiranes
Advanced Synthesis &Catalysis, EarlyView.The combination of azole compounds and oxiranes exhibits carbenoid reactivity at elevated temperatures, as demonstrated by the successful benzoin condensation of aromatic aldehydes. Using this catalytic system to polymerize bifunctional aldehyde/oxirane monomers yields thermosets with glass transition temperatures above 100°C.
