Abstract
Silylalkyldiamines react at 297 K with carbon dioxide to afford zwitterionic intramolecular sixmembered cyclic ammonium carbamates of formula RNH2 + CH2CH2NHCOO2, a unique example of CO2 uptake by an amine with a 1+1 molar ratio. Such systems may have a potential application in CO2 separation. The catalytic role of carbon dioxide in the carbamation of the above mentioned amines by reaction with organic carbonates is describedFile in questo prodotto:
