(Phenyl)iodonium Triflate. A New and Efficient Precursor of Benzyne
(Phenyl)iodonium triflate readily prepared from o-bis(trimethylsilyl)benzene and the hypervalent iodine(III) reagent shows excellent formation of benzyne under mild and neutral conditions and efficiently provides adducts with typical trapping agents, e. g. furan, anthracene, diphenylisobenzofuran and tetraphenylcyclopentadienone.
