TCDA: Practical Synthesis and Application in the Trifluoromethylation of Arenes and Heteroarenes was written by Wang, Jian;Zhang, Xiaomin;Wan, Zehong;Ren, Feng. And the article was included in Organic Process Research & Development in 2016.SDS of cas: 4457-67-4 This article mentions the following:
A practical synthesis of the reagent trimethylsilyl chlorodifluoroacetate (TCDA) is reported on a 50 g scale. The trifluoromethylation with TCDA was optimized, and the reaction shows very broad scope with respect to electron-deficient, -neutral, -rich aryl/heteroaryl iodides, as well as excellent functional group tolerability, such as ester, amide, aldehyde, hydroxyl, and carboxylic acid. The reagent was also applied to the late-stage trifluoromethylation of three medicinally relevant compounds Addnl., the building block trifluoromethylpyridine and one drug related mol. Boc-Fluoxetin were synthesized in 10 g scale by this method, demonstrating its practical applications in process chem. In the experiment, the researchers used many compounds, for example, 1-Bromo-4-methoxybutane (cas: 4457-67-4SDS of cas: 4457-67-4).
1-Bromo-4-methoxybutane (cas: 4457-67-4) belongs to organobromine compounds. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. For many applications, organobromides represent a compromise of reactivity and cost.SDS of cas: 4457-67-4
