The photobromination of ?-pinene at high temperature and synthesis of some pinene

Bisyclic terpenes are the natural substances and they are used in organic chemistry for synthesis of important compound. Especially like biological active-substance synthese and like colorants the bisyclic terpenes have a common usage. Especially the current studies about ?-pinene have been going on. The synthese performances which belong to ?-pinene-derivatives, that have a commercial importance, have been gaining importance. The compound of ?-pinene is a natural monoterpene which is used as a substrate for the production of flavour and flavor- monoterpenoids. The hydration and the asetoxylation of ?-pinene with the acid catalysis are the important ways for the synthesis of the terpenic alcohols and esters, which can be used in the perfume industry and pharrmasoptik industry.It can be seen that the arrangement productions about the literature workings on the compound of ?-pinene , are widely formed. In our work, we aimed the bromination with an effective and selective method for the derivation of ?-pinene-compound. After the different parameters applied the arrangement products and also normalcontribution productions. It is hoped that compounds obtained this method will trigger some future works.Key Words: Photobromination, ?-pinene, bisyclic monoterpenes, Wagner-Meervein rearrangement
