 EMI1.1
 



   The previously unknown bromoisovaleric acid esters of borneol and isoborneol can be represented according to the present invention in such a way that bromoisovaleric acid halide or anhydride is allowed to act on borneol or isoborneol, or bromoisovaleric acid in the presence of suitable condensing agents, such as. B. sulfuric acid, hydrochloric acid, phosphoric acid, with borneol or isoborneol for implementation.

   The isobornyl bromoisovalerate can also be obtained by adding bromoisovaleric acid to camphor in the presence of suitable condensing agents. such as zinc chloride, sulfuric acid, hydrochloric acid, phosphoric acid, nitric acid.
