PP-II-34NORBORNADIENE IN NEW SHAPE-SELECTIVE CATALYTIC SYNTHESESFlid V.R., Evstigneeva E.M., Dmitriev D.V.Lomonosov Moscow State Academy of Fine Chemical Technology, Moscow, RussiaE-mail: vflid@rol.ruA wide range of carbocyclic compounds, which are very difficult to synthesize viaconventional routes, can be manufactured through catalytic reactions with norbornadiene(NBD). These substances can be used as high-density fuels, special materials; they can beapplied in medicine, agriculture, microelectronics; besides, they are capable of accumulatingsunlight energy. NBD is derived from cyclopentadiene, a large volume byproduct ofpetrocemical processes like steam cracking. This is one reason why commercializing NBDbasedprocesses can help in creating wasteless technologies.NBD usually react through multiple routes giving rise to a number of products. Hence theselectivity of NBD-based reactions is of a primary importance.We have demonstrated the possibility to control the rate and the selectivity incyclodimerisation, co-dimerisation and allylation of NBD. Kinetic regularities have beenstudied and consistent mechanisms were developed.A series of unsaturates has been synthesized. These compounds possess a set of doublebonds with different reactivities, and hence they can be applied for creating modified rubbers.New co-dimerisation reactions between NBD and unsaturated esters and ketones, andsupercritical CO 2 , have been discovered and studied [1]. New polycyclic esters and lactoneshave been synthesized: they are applicable to a range of various purposes.Acknowledgements: authors are grateful to RFBR for financial support №№05-03-32258, 05-03-08134-ofi-a, 06-03-33091.References1.
