An efficient and recyclable tetraoxo-coordinated zinc catalyst for the cycloaddition of epoxides with carbon dioxide at atmospheric pressure

Abstract

Zn(OPO)2/TBAI was developed as a highly efficient and recyclable catalyst for CO2 conversion with a TOF up to 22 000 h−1.

Catalytic Conversion of CO2 to Cyclic Carbonates through Multifunctional Zinc‐Modified ZSM‐5 Zeolite

“…[5] Over the past few decades, many well-established homogeneous catalytic protocols including metal catalysis [6] and organocatalysis [7] have been reported for the reaction of epoxides and CO 2 . Among them, the most effective systems refer to the metal catalysis such as Al III -amino triphenolate scaffold, [8] Zn [9] or Al-salen, [10] and Mg-porphyrin [11] types. Until now, these catalysts are not applied in practice probably due to their large cost.…”

Copper(I)‐Catalyzed Four‐Component Coupling Using Renewable Building Blocks of CO2 and Biomass‐Based Aldehydes

“…[42] In our case, in addition to the synthesis of furyl-containing bis-oxazolidinone products 5a and 5b, we further investigated the preparation of furyl-containing poly-oxazolidinone 7 by the CuI-coupling of 1,3-diethynylbenzene furfural, 1,6-hexanediamine, and CO 2 (Scheme 3). [73] The bifunctional Cu II catalyst simultaneously activated both the two substrates propargylic amine and CO 2 , thus effectively promoting the carboxylative cyclization. Figure 1 shows a solid-state 13 C NMR spectrum of the 7.…”

Self‐Assembly of Luminescent Lanthanide Mesocates as Efficient Catalysts for Transforming Carbon Dioxide into Cyclic Carbonates

“…The turnover number (TON) value was determined to be up to 930 with a TOF value up to 124 h −1 . For comparison, these values reported for other catalytic systems operating under atmospheric pressure mostly fall within the range of less than 500 for the TON and less than 100 h −1 for the TOF . As far as we know, only three cases (i.e., a rare‐earth‐metal phenolate catalyst, a Zn–porphyrin catalyst, and a dinuclear Zn‐based metal–organic catalyst) showed relatively high TON and TOF values.…”
