Abstract:
The DBU-CO2 adduct was characterized for the first time by 13C NMR with labelled 13CO2 and IR spectroscopy. Theoretical calculations were crucial to determine that the adduct is stable in ionic liquid medium in the presence of water. These findings provide new insights into superbase-CO2 interactions, unveiling a new potential route to CO2 activation.

Conjugated dienes have lower heats of hydrogenation than cumulated and isolated dienes, making them more stable. The enhanced stabilization of conjugated systems can be understood from their π molecular orbitals.
The simplest conjugated diene is 1,3-butadiene: a four-carbon system where each carbon is sp2-hybridized and has an unhybridized p orbital that contains an unpaired electron. According to molecular orbital theory, atomic orbitals combine to form molecular orbitals such that the...
