The reactions of various types of organic bromides with a mixture of bicycloheptene or bicycloheptadiene and alkynes are reported. The products are bicyclic compounds, containing an organic chain and an alkynyl group in adjacent positions.

Palladium-catalyzed reaction of norbornene with allyl acetate gave 3-methylenetricyclo[4.2.1.0(2,5)]nonane 1 and 2-methylene-3-vinylnorbornane 2 in high yields. The substituents on allyl acetate strongly influenced the selectivity. In the reactions of 1- or 3-substituted allyl acetates, cycloadducts corresponding to 1 were obtained exclusively. Use of methallyl acetate gave solely a diene corresponding to 2. (C) 2000 Elsevier Science Ltd. All rights reserved.
