The (1α,2β,3α,6α)-2,3,7,7-tetrahalobicycloheptanes (8a-c), whose structures have been determined by X-ray methods, give 2-halobicyclohepta-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 (1α,3α,4β,6α)-3,4,7,7-tetrahalobicycloheptanes (3) give unrearranged 3-halobicyclo-hepta-1,3,5-trienes (4).
