Reactions of 3-halopropynols and their butadiyne analogues with BF3·Et2O or HX(aq) were investigated. Depending on the end group and the reaction conditions, different products were obtained which belonged to two classes: (i) 1,1-dihaloallenes, and (ii) products of 2+2 cycloaddition. The resulting species were identified using single crystal X-ray analysis and NMR spectroscopy.
