The reactions of 1,4-benzo-, naphtho-, and 9,10-anthraquinones with bis(perfluoroalkanoyl) peroxides gave the corresponding perfluoroalkylated derivatives. Those of 2-methyl- and 2-[4-(chloroanilino)]-1,4-naphthoquinones with bis(oxaperfluoroalkanoyl) peroxides afforded the dichloromethyl and trifluoromethyl derivatives, respectively. Absorption bands of the perfluoroalkylated naphtho- and anthraquinone dyes showed a slight hypsochromic shift. The solubilities of the perfluoroalkylated anthraquinone dyes into hexane were much more higher than those of the non-perfluoroalkylated ones.
