Abstract
Aromatski heterociklički spoj 1-benzotiofen, oksidacijom se prevodi iz sulfida u odgovarajući sulfon, 1 -benzotiofen-1,1-dioksid. U ovom radu 1 -benzotiofen je oksidiran u 1-benzotiofen-1,1-dioksid korištenjem vodene otopine vodikova peroksida i ledene octene kiseline kao otapala, uz refluksiranje i to u vrlo dobrom iskorištenju od 71 %. Oksidacija 1- benzotiofena je provedena i uz oksidirajući reagens H2O2-P2O5 i acetonitril kao otapalo, sa ili bez refluksiranja. Ovisno o metodi, iskorištenja su bila 3-48%. Korištenje H2O2-P2O5 reagensa je ekološki prihvatljivo i pokazalo se kao dosta dobro oksidacijsko sredstvo, koje se može primjeniti i za druge heterocikličke spojeve koji sadrže sumpor, a u slučaju 1 - benzotiofena osobito onda kada sadrži elektron-akceptorske skupine (EWG).
Abstract (english)
The aromatic heterocyclic compound 1-benzothiophene can be oxidized from its sulfide functional group into a sulfone, 1-benzothiophene-1,1-dioxide. In this work 1- benzothiophene is oxidized into 1 -benzothiophene-1,1-dioxide by heating an aqueous solution of hydrogen peroxide and glacial acetic acid as a solvent at reflux, with a very good yield of 71 %. Oxidation of 1-benzothiophene was carried out with H2O2-P2O5 reagent and acetonitrile as solvent, with and without reflux. Depending on the method, yields were ranging from 3-48%. The use of H2O2-P2O5 reagent is environmentally acceptable and it has been demonstrated to be a good oxidation agent which can be applied for other heterocyclic compound that contain sulfur, especially for 1-benzothiophenes that contain electron-withdrawing groups (EWG).
