    Abstract: A process for producing an unsaturated cyclic compound, comprising the steps of hydrochlorinating a terpene to produce a hydrochlorinated terpene, and subjecting the hydrochlorinate terpene to elimination of hydrogen chloride to form an unsaturated cyclic compound. The terpene is preferably &agr;-pinene, &bgr;-pinene, camphene or suitable turpentine fraction. The cyclic compounds can be used as monomers and by means of the invention it is thus possible to produce plastics from renewable raw material sources.

    Abstract: The invention relates to a process for the grafting a chain on to the 10-position carbon atom of a tricyclene skeleton, more particularly for producing 10-substituted stereospecific tricyclenes, especially cis-.alpha.-santalene and cis-.alpha.-santalol. The process involves the production of a sulphone of the tricyclene, the reaction of the sulphone with the halogenated derivative of the desired side chain and desulphonating the product.
