N-Arylation of Amines with o-Silylaryl Triflate

An efficient, transition-metal-free procedure for the N-arylation of amines 1 has been achieved by allowing those substrates to react with o-silylaryl triflate 2 in the presence of CsF. Good to excellent yields of arylated products 3 are obtained under very mild reaction conditions. This chemistry readily tolerates a variety of functional groups.
