N-Protonation vs O-Protonation in Strained Amides:  Ab Initio Study

open access: yes, 2016
Protonation plays an important catalytic role in amide bond hydrolysis. Although the protonation site of an amide is still debatable, O-protonation is generally preferred to N-protonation in ordinary amides.

Theoretical Study on the Protonation of Cucurbit[7]uril

open access: yesActa Chimica Slovenica, 2013
By using quantum mechanical DFT calculations, the most probable structures of the cucurbit[7]urilH3O+ and cucur-bit[7]uril'(H3O+)2 cationic complex species were derived. In these two complexes having a plane symmetry, each of the considered H3O+ cations
