2-Haloethynyl-2-norbomanols react with iodine and Koser's reagent in acetonitrile to afford two ring-expanded products, 2-[(Z)-haloiodomethylidene]bicyclo[3.2.1]octan-3-one and 3-[(Z)-haloiodomethylidene]bicyclo[3.2.1]octan-2-one. These results contrast with the 2-haloethynyl-2-bomanols which lead to the corresponding 3-octanones.
