Herein, a facile transition-metal-free approach to sulfur-containing heteroacenes e.g., dibenzo[b,d]thiophene from fluorinated oligophenylenes e.g., 2,2′-difluoro-1,1′-biphenyl was reported. Unlike most existing methods, the presented approach is not restricted to simple dibenzothiophene derivatives and thus appears to be a useful tool for the synthesis of extended sulfur-containing heteroacenes. The incorporation of sulfur is unambiguously preprogrammed via the positions of fluorines in the precursors, allowing the selective synthesis of extended thienoacenes with up to 96% yield. In the experiment, the researchers used many compounds, for example, Sodium 2-methyl-2-propanethiolate (cas: 29364-29-2Quality Control of Sodium 2-methyl-2-propanethiolate).
Sodium 2-methyl-2-propanethiolate (cas: 29364-29-2) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.Quality Control of Sodium 2-methyl-2-propanethiolate
