《Pentafluorophenyl compounds. I. Preparation and reactions of bis(pentafluorophenyl)cadmium》 was published in Chemische Berichte in 1967. These research results belong to Schmeisser, Martin; Weidenbruch, Manfred. Quality Control of Ethyl 2,3,4,5,6-pentafluorobenzoate The article mentions the following:
Cd(C6F5)2 (I) was prepared by thermal decarboxylation of Cd(O2CC6F5)2 or by treatment of C6F5Li with CdCl2. I formed 1:1-complexes with 2,2′-bipyridyl and 2,2′-biquinolyl. Treatment of I with BzCl yielded BzC6F5 (II), and I with AcCl gave AcC6F5. II was also obtained on treatment of I with C6F5COCl in C6H6, while in PhMe C6F5COC6H4Me was obtained. In the experiment, the researchers used many compounds, for example, Ethyl 2,3,4,5,6-pentafluorobenzoate(cas: 4522-93-4Quality Control of Ethyl 2,3,4,5,6-pentafluorobenzoate)
Ethyl 2,3,4,5,6-pentafluorobenzoate(cas: 4522-93-4) belongs to esters. Esters are more polar than ethers but less polar than alcohols. Quality Control of Ethyl 2,3,4,5,6-pentafluorobenzoate They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols.
