Abstract

An efficient electrophilic thiocyanation of phenols and anilines in the CeBr3 / H2O2 system has been developed. The system CeBr3 / H2O2 generates reactive brominating species which would react with NH4SCN to deliver the active SCN cations in situ. The Br- anion can be further oxidized to Br+, thereby furnishing the catalytic cycle.
