Vanadium(V) complexes derived from aminotriphenolate ligands are demonstrated to be highlyactivecatalysts for the coupling of various terminal and internal epoxides with carbon dioxide to afford a series of substituted organiccarbonates in good yields. Intriguingly, a V(V) complex bearing peripheral chloride groups on the ligand framework allowed for the formation and isolation of a rare complex
已证明衍生自氨基三酚盐配体的钒(V)络合物是高活性催化剂,可用于将各种末端和内部环氧化物与二氧化碳偶联,从而以高收率提供一系列取代的有机碳酸酯。有趣的是,在配体骨架上带有外围氯化物基团的V(V)络合物允许形成和分离稀有的络合物,该络合物结合了一个开环的环氧化物,其中酚盐-O原子之一作为亲核试剂,金属中心为刘易斯酸性位点。该异常结构通过X射线衍射和51 V NMR表征,并显示出对环氧丙烷和CO 2偶联的催化活性。当与这些底物进行后合成时。本文获得的结果清楚地表明,处于高氧化态的钒配合物是有效的催化剂,可用于活化具有挑战性的内部环氧化物并将其转化为环状有机碳酸酯。

A highlyregioselective catalytic approach has been developed towards carbamates derived from cyclic organic carbonates by reaction of the latter with amine reagents under organocatalytic control. For various combinations of carbonate and amine substrates, an organocatalyst (TBD: 1,5,7‐triazabicyclo[4.4.0]dec‐5‐ene) was used to increase the reaction kinetics while exerting excellent regioselective control
Highly efficient conversion of CO<sub>2</sub> to cyclic carbonates with a binary catalyst system in a microreactor: intensification of “electrophile–nucleophile” synergistic effect
An intensification of the “electrophile–nucleophile” synergistic effect was achieved in a microreactor for the coupling reaction of CO2 and epoxides mediated by the binary Al complex/ternary ammonium salt catalyst system.
The synthesis of propylene carbonate from propylene oxide and carbon dioxide under supercritical conditions in the presence of 1-octyl-3-methylimidazolium tetrafluoroborate was achieved in nearly 100% yield and 100% selectivity within 5 minutes, whose TOF value is 77 times larger than those so far reported.
