Recent advances in chemical fixation of CO2 based on flow chemistry

Multimode Photo-CSTR (Continuous Stirred Tank Reactor) Setup for Heterogeneous Photocatalytic Processes

“…Another photocatalyzed multiphasic reaction for carboxylation of diaryl ketone was conducted in vertical flow mode, which employs the equivalent amount of inorganic base as solid and CO 2 as gaseous phase (Figure C). Despite the fact that inorganic bases are inclined to clog the flow systems, the process ran smoothly using our setup on a gram scale without any clogging, further indicating the effectiveness of the continuously stirred flow system.…”

A superhydrophobic MOF facilitating efficient solvent-free catalytic chemical fixation of CO2 and oxidation of hydrocarbons and MOF@cotton@starch composite-based selective sensing of a herbicide

“…However, the chemical fixation of CO 2 is always challenging due to the kinetic inertness of CO 2 and high CQO bond enthalpy (805 kJ mol À1 ). 3 Various chemical fixation strategies 4 have been proposed, including entrapping CO 2 in an epoxide ring to produce cyclic carbonate. This process gained huge importance due to the potential application of cyclic carbonates as fuel additives and electrolytes.…”

Zinc-mediated carboxylations of allylic and propargylic halides in flow: synthesis of β-lactones via subsequent bromolactonization

“…1 However, the use of CO 2 has become increasingly explored as a C1 electrophile, particularly for allylic carboxylations. 8 Previous methods for allylic carboxylation of aryl or alkyl zinc reagents employ Pd, Ni or Cu-based catalysts, high temperatures, and occasionally high-pressure conditions through transmetalation of allyl tin, boron, or zinc reagents ( Scheme 1a ). 9 In addition, oxidative addition strategies of allylic halides, alcohols, and acetates for allylic carboxylation were described by Torii, 10 Martin, 11 Mita, 12 and Nicholas.…”
