Functionalization at the double bond region of jojoba oil: I. bromine derivatives

Addition of bromine to jojoba oil and its trans-isomer yielded tetrabromojojoba, which upon elimination afforded the acetylenic and allenic components, respectively, when reacted with excess of base. The bromoolefinic products were obtained when limited amount of base was used. Allylic bromination of the liquid wax and its trans-isomer, and subsequent HBr elimination, yielded the two conjugated diene systems on both parts of the ester (jojoba tetraene).
