Abstract
An efficient route to carbazoles and dibenzofurans has been developed. The reaction of o-iodoanilines or o-iodophenols with silylaryl triflates in the presence of CsF to afford N- or O-arylated products is followed by a cyclization using a Pd catalyst to carbazoles and dibenzofurans in good to excellent yields. Various functional groups are tolerated.
