title: Polycyclic croissant-like organic compounds are powerful superbases in the gas phase and acetonitrile--a DFT study.
abstract: A new type of the π-electron polycyclic organic superbases is proposed exhibiting very high proton affinities in the gas phase spanning the range from 280 to 323 kcal mol(-1) and the pK(a) up to 41.4 units in the MeCN solutions. Their salient feature is formation of the (H(+))-bridge upon protonation and a strong cationic resonance effect in the corresponding conjugate acids.
