In 2022,Kreisel, Tatjana; Mendel, Marvin; Queen, Adele E.; Deckers, Kristina; Hupperich, Daniel; Riegger, Julian; Fricke, Christoph; Schoenebeck, Franziska published an article in Angewandte Chemie, International Edition. The title of the article was 《Modular Generation of (Iodinated) Polyarenes Using Triethylgermane as Orthogonal Masking Group》.Quality Control of 2,5-Dibromothiophene The author mentioned the following in the article:
Herein, a complementary modular coupling approach to the widely employed Suzuki coupling strategy of boron containing precursors, which relied on organogermane containing building blocks as key orthogonal functionality and an electrophilic (rather than nucleophilic) unmasking event paired with air-stable PdI dimer based bond construction was disclosed. This allowed to significantly shorten the reaction times for the iterative coupling steps and/or to close gaps in the accessible compound space, enabling straightforward access also to iodinated compounds In the experimental materials used by the author, we found 2,5-Dibromothiophene(cas: 3141-27-3Quality Control of 2,5-Dibromothiophene)
2,5-Dibromothiophene(cas: 3141-27-3) , is mainly used as pharmaceutical intermediate and synthesis intermediate. 2,5-Dibromothiophene polymerizes by debromination with magnesium catalyzed by nickel compounds to form poly(2,5- thienylene) .Quality Control of 2,5-Dibromothiophene
