| Research Abstract |
Aromatic (including heterocyclic) compounds having fluorine-containing functional groups (ArX : X=F, OSO_2CF_3, OSO_2F, OCOCF_3) have been prepared in good yields by the diazotization of the corresponding aminoarenes (ArNH_2) and the thermal or photochemical decomposition in situ in fluorine containing strong acids (HX) with or without bases, or dediazoniation of arenediazonium tetrafluoroborate salts (ArN_2BF_4) in HX-(Base).
Novel arenediazonium of triflates (ArN_2BF_4) have been prepared in good yields by nonaqueous state diazotization of ArNH_2 in EtOH with isoamyl nitrate in CF_3SO_3H. Decomposition of ArN_2OTr will be also described to afford the corresponding ArOSO_2CF_3.
