Vlasov, V. M.’s team published research in Zhurnal Organicheskoi Khimii in 1973 | CAS: 4522-93-4

Ethyl 2,3,4,5,6-pentafluorobenzoate(cas: 4522-93-4) belongs to esters. They are important in biology, being one of the main classes of lipids and comprising the bulk of animal fats and vegetable oils.Formula: C9H5F5O2 Polyesters are important plastics, with monomers linked by ester moieties.

The author of 《Aromatic fluoro derivatives. XLVI. Reaction of pentafluorophenyl derivatives of methane with triphenylmethyl tetrafluoroborate》 were Vlasov, V. M.; Koifman, P. I.; Yakobson, G. G.. And the article was published in Zhurnal Organicheskoi Khimii in 1973. Formula: C9H5F5O2 The author mentioned the following in the article:

C6F5CHCl2 and C6F5CHF2 were unreactive toward Ph3C+ BF4- at 35-60° in CH2Cl2 or ChCl3 containing C6H6, but C6F5CH(OH)Me yielded Ph3CH, Ph3COH, C6F5COMe, and C6F5CHMeOCPh3 under similar conditions; Ph3C+ BF4- and C6F5CH(oEt)2 afforded C6F5CHO and Ph3CH as the major product at 23-5°, along with C6F5CO2Et, Ph3COEt, and MeCHO. A mechanism involving H- transfer was proposed for these reactions. In the experiment, the researchers used Ethyl 2,3,4,5,6-pentafluorobenzoate(cas: 4522-93-4Formula: C9H5F5O2)
