Sažetak
Design of new powerful neutral superacids is of great importance in organic chemistry. It is shown by using a reliable theoretical model that cyano derivatives of fulvene provide very good candidates for potent organic superacids. The origin of the high acidity is identified as the aromatization of the five-membered ring upon deprotonation. Their acidity is enhanced by the Lewis acid-base interaction between a -CH2-CH2-CH2-BX2 chain and the anionic O- center in the corresponding conjugate bases. X stands here for F, Cl and Br atoms. There are good reasons to believe that the proposed neutral organic superacids are amenable to laboratory preparation.
