摘要

Abstract: A short procedure for the synthesis of 2, 2-di (3-thienyl)-1, 3-dioxolan is described. The route developed is convenient (only two synthetic and one chromatographic steps are required) and efficient (66% overall yield from 3-bromothiophene). This compound was transformed into the ketone, cyclopenta [2, 1-b: 3', 4'-b'] dithiophen-4-one by a known process. Optimized syntheses of symmetric aryl ketones, 1-alkyl-3-methylimidazolium and ...
