1271-42-7, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. Ferrocenecarboxylic acid, cas is 1271-42-7,the iron-catalyst compound, it is a common compound, a new synthetic route is introduced below.
Ferrocenecarbonyl chloride was prepared in a schlenk line system to ensure moisture free environment as reported before [21]. In a typical reaction, ferrocene carboxylic acid (10.3601 g, 45.0 mmol) was firstly dried under vacuum at 50 C for 30 min and then dissolved in 75.0 mL of freshly distilled DCM. After that, pyridine(7.20 mL, 90.36 mmol) was added to the previous solution followed by the dropwise addition of oxalyl chloride (7.75 mL, 90.36 mmol) at 25 C. The reaction mixture was stirred for 30 min first at 25 C and then refluxed for 5 h. The contents of the reaction flask were evaporated under vacuum and petroleum ether (80.0 mL) was added. The mixture was stirred for 2 h at 90 C at this stage. At last, the solvent was evaporated to get the dried ferrocene monocarbonyl chloride.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of Ferrocenecarboxylic acid, 1271-42-7
