(3-Ammonio-2,2-dimethyl-propyl)carbamate Dihydrate

Abstract

(3-Ammonio-2,2-dimethylpropyl)carbamate dihydrate was synthesised. The title compound was characterised by single crystal X-ray diffraction and IR-/Raman-spectroscopy. It has been demonstrated that a mixture of dilute acetic acid and 2,2-dimethyl-1,3-diaminopropane is able to capture CO2 spontaneously from the atmosphere. An intramolecular hydrogen bond stabilises the conformation of the ylide-type title molecule. Intermolecular hydrogen bonds between all moieties connect them to a strand-type chain structure.

“…Consequently, dmpn and ligands with a similar topology have a broad scope application such as their use as bridging ligands in metal organic frameworks and in coordination polymers [7,8]. Recently we reported the interesting finding that dmpn is able to capture CO 2 spontaneously by the formation of (3-ammonio-2,2-dimethyl-propyl)carbamate dihydrate [9]. The carbamate releases its CO 2 on heating which might add some applications.…”
