The reaction between epoxide and cyanurate is believed to consist of the insertion of the epoxide into the triazine ring-oxygen bond, followed by isomerization; However, definitive evidence has not yet been obtained. Therefore, in this study, we investigated the reaction behavior using model systems for both the insertion and isomerization processes. We found that the insertion step could be promoted by adding 4-dimethylaminopyridine, while the isomerization step could be facilitated by the addition of ethylene glycol, a protic polar compound.
