Observation of guanidine-carbon dioxide complexation in solution and its role in reaction of carbon dioxide and propargylamines [PDF]
, 2014 The first observation of guanidine-CO2 'activation' complexes in solution using ATR-FTIR is reported. While cyclic guanidines TBD and MTBD form stable and detectable complexes with CO2, other guanidines and tertiary amines do not.
