摘要：

Amidines have been reported to react with CO2 to form a stable and isolable zwitterionic adduct but previous studies were performed in the presence of at least some water. However, spectroscopy of the reaction between DBU and CO2 detects the rapid formation of the bicarbonate salt of DBU when wet DBU is exposed to CO2 and does not indicate that an isolable zwitterionic adduct between DBU and CO2 forms either in the presence or the absence of water. © 2005 American Chemical Society.
