Purification Methods

2,3-Dimethylbenzothiophene [31317-17-6] M 212.3, m 69-70o, b 123-124o/10mm, n D 1.6171. Fractionate it through a 90cm Monel spiral column, or other efficient fractionating or spinning band column and collect the middle fraction. It has also been purified by chromatography on basic alumina using pentane as eluent. [Tedjanulia et al. J Heterocycl Chem 20 1485 1983, Beilstein 17 III/IV 161.]

SCHWEFELVERBINGUNGEN DES ERDOELS XVIII. DIALKYLDIBENZOTHIOPHENE

The preparation of 2,8-, 2,6-, 2,3- and 4,6-dialkyldibenzothiophenes and of the corresponding 5,5-dioxides is described. 1H-NMR-data and GC-purities are given. Key words: Dimethyldibenzothiophenes; diethyldibenzothiophenes; 2,8-dipropyldibenzothiophene; 2,8-dibutyldibenzothiophene; 2,8-diisobutyldibenzothiophene; 3-ethyl-2-methyldibenzothiophene; dialkkyldibenzothiophene-5,5-dioxides.

The Synthesis of All of the Dimethyldibenzothiophenes and Monoethyldibenzothiophenes

The synthesis of all four isomers of the monoethyldibenzothiophenes and all of the sixteen isomers of the dimethyldibenzothiophenes has been accomplished.
