%X The (1&#945;,2&#946;,3&#945;,6&#945;)-2,3,7,7-tetrahalobicyclo[4.1.0]heptanes (8a-c), whose structures have been determined by X-ray methods, give 2-halobicyclo[4.1.0]hepta-1,3,5-trienes (5) upon dehydrohalogenation. The 'mixed' halide (8c) and partly labelled [7-13c]-(8b,c) have revealed the presence of competing pathways in these conversions. By comparison, dehydrohalogenations of the (1&#945;,3&#945;,4&#946;,6&#945;)-3,4,7,7-tetrahalobicyclo[4.1.0]heptanes (3) give unrearranged 3-halobicyclo[4.1.0]-hepta-1,3,5-trienes (4).
