    摘要: The unsaturated bicyclic hydrocarbons of formula
    possessing a double bond in one of the positions indicated by the dotted lines (n = zero or 1; R = H or methyl) are prepared from the compounds of formula
    (R = H or methyl) by reacting them with a triaryl-pnosphi- ne in the preserce of a metal ha de and cptionally treating the obtained product with an isomenzing agent.
    Compounds (I) are useful intermediates in the synthesis of macrocyclic ketones
