چکیده انگلیسی
Hexasubstituted benzene derivatives, aromatic triols 4, 9 and triacids 5, 10 have been synthesized from oleic and erucic acid derivatives followed by a cyclotrimerization step catalyzed by palladium-on-carbon (Pd/C) and chlorotrimethylsilane (TMSCl). The asymmetric isomer, which is the main product, was isolated from its symmetric isomer by flash chromatography. All the products were fully characterized by IR, 1H NMR, 13C NMR and mass spectrometry. The products are suitable monomers for the production of polyurethanes, polyesters and polyamides.
