1,6-Dibromotricyclo[3.1.0.02,6]hexane 2e has been prepared in 56% yield by reaction of 1,6-dilithiotricyclo[3.1.0.02,6]hexane 2d with 2.5 equiv. of tosyl bromide. 2e proved to be a new source for generating tricyclo[3.1.0.02,6]hex-1-(6)-ene 1 by reaction with magnesium, with lithium sand, or with tert-butyllithium, as shown by formation of the Diels-Alder adduct 5. Ene adducts of 1 were obtained with
