UNUSUAL REACTIVITY OF PENTAFLUOROBENZYL AROMATIC ETHERS UNDER FRIEDEL-CRAFTS REACTION CONDITIONS

Xu, Linxiao,Giese, Roger W.

, p. 3829 - 3832 (1993)

A pentafluorobenzyl (PFBz) ether of 2,6-dimethylphenol undergoes a PFBz rearrangement, which appears to be intermolecular, yielding a 2:3 ratio of meta to para migration.Only ether bond cleavage takes place in a corresponding PFBz ether of 2,6-difluorophenol.Both sets of products are unusual, and it is suggested that they are both due to high reactivity of the PFBz-oxy moiety with the AlCl3 catalyst.
