Recent progress in the catalytic transformation of carbon dioxide into biosourced organic carbonates

Abstract

The recent advances made in the catalytic preparation of biobased cyclic carbonates derived from sugars, glycerol, fatty acids/vegetable oils and terpenes are presented, together with a discussion surrounding their potential applications.

Strategies for Integrated Capture and Conversion of CO2 from Dilute Flue Gases and the Atmosphere

“…Ethylene can be more sustainably synthesized from the dehydrogenation of bioethanol to form bioethylene, whereas biopropylene can be produced through the dimerization of bio‐ethylene to butene, which further react with the excess ethylene through metathesis reaction to form propylene [43b,44] . Cyclic carbonates can also be prepared from bio‐sourced feedstock, such as carbohydrates, glycerol, fatty acid and terpenes, as recently reviewed [45] …”

Crosslinked porous polyimides: structure, properties and applications

“…The synthesised polyimide performed as recyclable catalyst for the epoxidation of styrene using iodosylbenzene as the oxidant; however, the recyclability was only partially effective as most of the catalytic activity was lost after three reaction cycles. Considering the excellent catalytic activity of Lewis acidic centres in metalloporphyrins for the cycloaddition of CO 2 to epoxides, 113,114 it is expected that appropriately designed and constructed pPI catalysts would perform well in this reaction; 115,116 to the best of our knowledge, these promising materials have not yet been explored for this specific application.…”

One-Pot Tandem Catalytic Epoxidation—CO2 Insertion of Monounsaturated Methyl Oleate to the Corresponding Cyclic Organic Carbonate

“…Although recent studies suggest that only less than 1% of CO 2 generated from anthropogenic emissions can be effectively recycled into chemicals [1,2] and that other trapping strategies are needed to reduce excess CO 2 , nonetheless the preparation of COCs via the catalytic activation of CO 2 remains one of the most efficient strategies in green organic synthesis for its exploitation as a C1 building block and for its fixation into stable organic products and/or polymers [3]. This is even truer when renewable bio-based feedstocks such as glycerol, carbohydrates, terpenes and vegetable oils (VOs) are used [4]. The latter class, in particular, is interesting for multiple reasons which include the large commercial availability of VOs up to 200 MT per year [5], the relatively easy transesterification of vegetable oils into their components as fatty acids methyl esters (FAMEs) through the biodiesel manufacture, and the use of VOs as intermediates for a plethora of chemical compounds [6].…”
