I found the field of Chemistry very interesting. Saw the article A Facile Transition Metal-Free Ionic Liquid [BMIM]OH Mediated Regio- and Stereoselective Hydrocarboxylation of Alkynylnitriles published in 2021. Formula: C7H4F2O2, Reprint Addresses Goswami, A (corresponding author), Indian Inst Technol Ropar, Dept Chem, Nangal Rd, Rupnagar 140001, Punjab, India.. The CAS is 385-00-2. Through research, I have a further understanding and discovery of 2,6-Difluorobenzoic acid
We report an efficient and straight forward access to nitrile substituted enol esters via ionic liquid [BMIM]OH mediated hydrocarboxylation of alkynylnitriles under mild conditions. This atom economical transition metal-free protocol gives an easy access to a variety of such enol esters with excellent regio and Z-stereoselectivity. Reusability of [BMIM]OH without losing of significant amount of yield is another noticeable feature of this article.
Formula: C7H4F2O2. About 2,6-Difluorobenzoic acid, If you have any questions, you can contact Kumari, C; Goswami, A or concate me.
