| titleOfInvention | Method of catalytic isomerization of endotetrahydrodicyclopentadiene to exo-tetrahydrodicyclopentadiene |
| abstract | FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to a method of synthesis of exo- tetrahydrodicyclopentadiene that can be used as a hydrocarbon fuel and parent monomers for synthesis of biologically active substances. Method involves the isomerization reaction of endo-tetrahydrodicyclopentadiene to exo-tetrahydrodicyclopentadiene when polychloromethane is added by drops to a reaction mass consisting of endo-tetrahydrodicyclopentadiene, an inert solvent and an organoaluminum compound. Chelate or salt of transient metal: PdCl 2 ,Pd(acac) 2 ,Ni(acac) 2 . is used as a catalyst. Reaction is carried in argon atmosphere, under normal pressure and at temperature 10-60 C for 15-60 min. The mole ratio endo- tetrahydrodicyclopentadiene : organoaluminium compound : poly-chloromethane : salt (chelate) of metal = 100:9:32:0.1, respectively. Invention provides the development of the effective catalytic system providing 99.5% of the yield of the end product. EFFECT: improved method of isomerization, increased yield. 1 tbl, 7 ex |
