Zhang, Shaofei published the artcileUnlocking the Friedel-Crafts arylation of primary aliphatic alcohols and epoxides driven by hexafluoroisopropanol, Formula: C8H10O2, the main research area is alc preparation regioselective; epoxide arene ring opening Friedel Crafts arylation Bronstedacid catalyst; arylethane preparation; aliphatic alc arene Friedel Crafts arylation Bronsted acid catalyst.
The limitations thar easily overcome using Bronsted acid catalysis in hexafluoroisopropanol (HFIP) as a solvent were reported. Electron-poor aromatic epoxides and aliphatic epoxides undergo stereospecific arylation to give alcs. RC(R1)(Ar)CH2OH/RCH(OH)CH(Ar)OH, and based on the reaction conditions, it can partake in a second nucleophilic substitution with a different arene ArH in one pot. Ph ethanols R3(CH2)2OH (R3 = Ph, 2,6-dichlorophenyl, 2,4,6-trimethylphenyl, etc.) react through a phenonium intermediate, whereas simple aliphatic alcs. e.g., cyclopentanol participate in a rare intermol. SN2 Friedel-Crafts process, delivering linear products e.g., 1,3,5-trimethyl-2-phenethylbenzene exclusively. In this work, an alternative to metal-catalyzed cross-couplings was provided for accessing important scaffolds, and widening the range of applications of the Friedel-Crafts reaction.
