Reaction of allylic, benzylic and tertiary alkyl halides with zinc oxide in protic solvents leads to the formation of the corresponding alcohol, ethers and esters in good yields. The scope and limitations of this reaction have been examined. The possible involvement of ion quadruplets in the reaction is suggested.

A simple protocol involving the activation of DMSO by chlorotrimethysilane is described for the chemoselective chlorination of polyprenoids. The proposed protocol provides a versatile and scalable alternative to existing routes for accessing useful synthetic synthons for the synthesis of complex terpenoids.
