One-Electron Oxidation and Triphenylmethylation of Benzimidazolines by the Triphenylmethyl Cation

Article abstract of DOI:10.1007/BF01170747

With triphenylmethyl perchlorate (tetrafluoroborate) 1,2,2,3-tetrasubstituted benzimidazolines undergo electrophilic triphenylation at position 5.In further reaction with the electrophilic agent the obtained 5-triphenylmethylbenzimidazolines are converted into radical-cations.They undergo a similar transformation during the action of silver perchlorate and molecular oxygen.The results from investigation of the radicalcations by ESR and PMR are given.
