Abstract

original image

Simpel, sauber, sicher: Disubstituierte Harnstoffderivate lassen sich effizient aus Aminen und CO2 synthetisieren mit einem Katalysatorsystem aus CsOH in einer ionischen Flüssigkeit (IL). Die Produkte sind leicht abtrennbar, und das Katalysatorsystem kann ohne Desaktivierung wiederverwendet werden (siehe Bild).
