Abstract

Electrophilic intramolecular twofold iodoarylation was developed from the reaction of diynes and diynyl diethers and amines with iodine monochloride under mild conditions, which produced bis (2 H-hydronaphthalene and chromene) and 2 H-quinoline bearing an alkenyl iodide moiety in good to excellent yields. These compounds underwent Pd-catalyzed cross- coupling reactions with arylboronic acid and indium tris (arylthiolate) to produce the ...
