The ratios of nucleophilic substitution versus [3,3] sigmatropic rearrangement for the collapse of allenyl(aryl)-iodine(III), generated from the reaction of aryliodanes with propargylsilanes in the presence of BF3- Et2O in alcohols, were determined. A proposed mechanism involves generation of propargyl cations from the allenyliodine(III) via a unimolecular pathway.
