Abstract

Abstract The reaction of various organic and inorganic acids (HX) with iodonium ylides 2 leads to nucleophilic substitution of the iodobenzene substituent by the anion X− to yield the heterocycles 5. Some of them are hydrolyzed to the hydroxy compounds 3 or reduced to the starting compounds 1 under the reaction conditions. Reaction of the iodonium ylide 2b with monomethyl sulfate gives the salt 9, which with bases undergoes nucleophilic substitution ...
