Cleaner Routes for Friedel-Crafts Acylation [PDF]
, 2010 Friedel-Crafts acylation is among the most fundamental and useful reactions to yield aromatic ketones but it is one of the less acceptable in terms of unwanted polluting by-products or atom economy because of the overconsumption of catalyst which is used

Continuous Formation of Limonene Carbonates in Supercritical Carbon Dioxide
Organic Process Research & Development, 2022 We present a continuous flow method for the conversion of bioderived limonene oxide and limonene dioxide to limonene carbonates using carbon dioxide in its supercritical state as a reagent and sole solvent. Various ammonium- and imidazolium-based ionic liquids were initially investigated in batch mode.

Enzymatic Interesterification in Supercritical Carbon Dioxide
Agricultural and Biological Chemistry, 1988 An enzymatic reaction with supercritical carbon dioxide (SCCO2) as the reaction medium was investigated. Lipase could catalyze the batch type reaction of hydrolysis and interesterification (acidolysis) in SCCO2 at 50°C and 29.4 MPa. The time course of interesterification was influenced by the water content as well as by the kind of reaction medium. The
