Sustainable valorisation of renewables through dialkyl carbonates and isopropenyl esters

Abstract

This review showcases a thorough analysis of reactions and applications of the most widespread linear and alkylene organic carbonates (DACs) as dimethyl-, diethyl-, ethylene-, and propylene- carbonates (DMC, DEC, EC,...

K2CO3-Modified Smectites as Basic Catalysts for Glycerol Transcarbonation to Glycerol Carbonate

“…In this situation, it is of high interest to perform a more in-depth assessmen under relevant operational conditions but using flow or continuous reactors for a high operational time. Furthermore, the modest reductions in glycerol carbonate yield observed during the recycling and reuse processes, along with previous research findings [29][30][31], indicate tha leaching of K from our catalyst particles is not a significant concern. A similar conclusion is also supported by Figure 17 below, which underlines the high stability of smectite based catalysts.…”

Alkyl radicals from diacyl peroxides: metal-/base-/additive-free photocatalytic alkylation of N-heteroaromatics

“…DMC is also known as a potential methylating reagent under elevated temperature (∼90 °C). 33 In our reaction system, no methylation process was detected by TLC, GCMS, and HRMS, indicating that DMC is stable in this reaction. On the other hand, similar yields of the product were obtained when the model reaction was conducted in CH 3 CN and DMC (Table 1, entry 5 vs. entry 8), suggesting that DMC is not a unique solvent for this transformation.…”

Photocatalyst-free hydrothiolation of gem-difluoroalkenes with thiols

“…The use of green solvent DMC also proved to be efficacious, achieving a noteworthy yield of 70% (entry 7). Considering its benign environmental profile, 9 DMC was subsequently selected as the preferred solvent for ongoing experimentation. The stoichiometry of the reactants was also optimized (entries 10–12).…”
