Procedure

By the procedure described in Example 13, from 6-methyl-5-decen-2-one and vinyl-magnesium bromide there is obtained 3,7-dimethyl-1,6-undecadien-3-ol; nD26 = 1.4618, boiling point 116° C./9 mm Hg. This alcohol is reacted with phosphorus tribromide by the procedure of Example 13 to give 1-bromo-3,7-dimethyl-2,6-undecadiene.
