Polycyclic fluoroaromatic compounds. Part V. Nucleophilic replacement in decafluorophenanthrene
Abstract
Decafluorophenanthrene reacts with sodium methoxide and with dimethylamine with replacement of the fluorine atoms at positions 2 and 7. This has been proved by n.m.r. spectroscopy and by chemical means. Polyfluorophenanthrenes are oxidised to polyfluorobiphenyl-2,2′-dicarboxylic acids by potassium permanganate.
