An Efficient Procedure for the Synthesis ofortho-Trialkylsilylaryl Triflates: Easy Access to Precursors of Functionalized Arynes

o-Trialkylsilylaryl triflates, which are useful aryne precursors, are prepared from o-bromophenols by an efficient, one-pot procedure involving O-silylation, metal-halogen exchange, O- to C-silyl migration, and entrapment of the phenoxide with triflic anhydride.
