摘要: (Phenyl)[o-(trimethylsilyl)phenyl]iodonium triflate readily prepared from o-bis(trimethylsilyl)benzene and the hypervalent iodine(III) reagent [Phl(OAc)2·2TfOH] shows excellent formation of benzyne under mild neutral conditions efficiently provides adducts with typical trapping agents, e.g. furan, anthracene, diphenylisobenzofuran tetraphenylcyclopentadienone.
