Lewis acid catalysis in a supercritical carbon dioxide (scCO2)-poly(ethylene glycol) derivatives (PEGs) system: remarkable effect of PEGS as additives on reactivity of Ln(OTf)3-catalyzed Mannich and aldol reactions in scCO2
Abstract
Use of poly(ethylene glycol) derivatives (PEGs) as additives
in supercritical carbon dioxide (scCO2) was found to be
effective for Mannich and aldol reactions of silyl enolates with
