Ferrocenecarboxylic acid, cas is 1271-42-7, it is a common heterocyclic compound, the iron-catalyst compound, its synthesis route is as follows.,1271-42-7
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.
With the rapid development of chemical substances, we look forward to future research findings about Ferrocenecarboxylic acid
