Cycloaddition of arynes with iodonium ylides: a mild and general route for the synthesis of benzofuran derivatives.
A mild and general cycloaddition of arynes with iodonium ylides protocol has been developed for the synthesis of benzofurans. In the presence of CsF, ortho-silyl aryltriflates were reacted with iodonium ylides smoothly at room temperature in moderate to good yields.
