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)
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.
