Sulphur-doped porous carbon from a thiophene-based twin monomer.

Sulphur-doped carbon was synthesized using a thiophene-based twin monomer. While tetra(thiophene-2-ylmethoxy)-silane can be converted into sulphur containing nanocomposites, which lead to microporous sulphur-doped carbon, it is possible to produce additional mesopores by the use of templates. Thus, a variety of sulphur-doped carbon materials with tailored pore texture are available.

Synthesis of 5-acetoxymethyl- and 5-hydroxymethyl-2-vinyl-furan.

5-Acetoxymethyl- and 5-hydroxymethyl-2-vinylfuran were synthesized by two routes. The first route starts from 2-methylfuran and the second from furfuryl acetate. The latter route, involving successive Vilsmeier-Haack and Wittig reactions, is suitable for producing 5-acetoxymethyl-2-vinylfuran and 5-hydroxymethyl-2 vinylfuran in 68% and 60%yields, respectively.
