Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 4-(Hydroxymethyl)-1,3-dioxolan-2-one, is researched, Molecular C4H6O4, CAS is 931-40-8, about ONO pincer type ligand complexes of Al(III) as efficient catalyst for chemical fixation of CO2 to epoxides at atmospheric pressure.Safety of 4-(Hydroxymethyl)-1,3-dioxolan-2-one.
A series of ONO pincer hydrazone based most active mono-nuclear Al(III) complexes was successfully synthesized and characterized with the help of NMR, IR and mass spectrometry and only one complex with thiophen-2-yl group was confirmed by single-crystal anal. The synthesized Al(III) complexes were then employed as capable catalysts for the solvent-free chem. fixation of CO2 with epoxides I (R1 = CH3, CH2Cl, Ph, CH2=CH, etc.) at atm. pressure and could be reused five times without loss of any catalytic activity. In addition, the catalytic mechanism was investigated by analyzing intermediates via 1H NMR, 13C NMR, and mass MALDI-TOF. The excellent catalytic performance could be due to simultaneous attack and the opening of the epoxide by metal centers to form an alkoxide ion which activates the CO2 the same time.
In some applications, this compound(931-40-8)Safety of 4-(Hydroxymethyl)-1,3-dioxolan-2-one is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
