Solution photolysis of geranyl and neryl iodides, and 2(E),6(E)- and 2(Z),6(E)-farnesyl iodides has been carried out.Products arising from simple elimination as well as ?-participation are formed.Thus, both geranyl and neryl iodides furnished, besides some unidentified compounds, myrcene, cis-ocimene, limonene and terpinolene, though in different proportions.Likewise, the sesquiterpene analogues yielded different amounts of trans-β-farnesene, β-bisabolene, trans-α-bisabolene and ar-curcumene.Results have been discussed in terms of ionic intermediates.
