So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Mesias-Salazar, Angela; Martinez, Javier; Rojas, Rene S.; Carrillo-Hermosilla, Fernando; Ramos, Alberto; Fernandez-Galan, Rafael; Antinolo, Antonio researched the compound: 4-(Hydroxymethyl)-1,3-dioxolan-2-one( cas:931-40-8 ).Synthetic Route of C4H6O4.They published the article 《Aromatic guanidines as highly active binary catalytic systems for the fixation of CO2 into cyclic carbonates under mild conditions》 about this compound( cas:931-40-8 ) in Catalysis Science & Technology. Keywords: aromatic guanidine catalyst preparation epoxide carbon fixation; cyclic carbonate preparation epoxide carbon fixation aromatic guanidine catalyst. We’ll tell you more about this compound (cas:931-40-8).
We have synthesized a set of aromatic mono- and bis(guanidines) which are highly effective binary catalytic systems (guanidine/cocatalyst) for the formation of cyclic carbonates. The presence of multiple N-H bonds causes a modification in the traditional mechanism proposed for the synthesis of cyclic carbonates catalyzed by guanidines through the formation of hydrogen bonds between the oxygen atom of the epoxide and the N-H groups of the guanidines. This change allows a considerable reduction of the reaction temperature and CO2 pressure employed in this process.
The article 《Aromatic guanidines as highly active binary catalytic systems for the fixation of CO2 into cyclic carbonates under mild conditions》 also mentions many details about this compound(931-40-8)Synthetic Route of C4H6O4, you can pay attention to it, because details determine success or failure
