Zinc–gold cooperative catalysis for the direct alkynylation of benzofurans [PDF]
Beilstein Journal of Organic Chemistry, 2013 The direct alkynylation of benzofurans was achieved for the first time using the hypervalent iodine reagent 1-[(triisopropylsilyl)ethynyl]-1,2-benziodoxol-3(1H)-one (TIPS-EBX) based on the cooperative effect between a gold catalyst and a zinc Lewis acid.
