S. Nikas et al., The reaction of trimethylsilylethynyl(phenyl)iodonium triflate with some phenolates: Formation of substitution and sp(2) C-H insertion products, MOLECULES, 5(11), 2000, pp. 1182-1186
Treatment of trimethylsilylethynyl(phenyl)iodonium triflate with the potass
ium salts of some acidic phenols results in the formation of substitution p
roducts (O-trimethylsilylethynylphenols and/or O-ethynylphenols), along wit
h sp(2)C-H insertion products which afford eventually 2-aroxybenzo[b]furans
