Synthetic methods for introduction of two substituents into the rings of octafluoroparacyclophane are presented. Nitration gives three isomers with nitro substituents on different rings: pseudoortho, pseudo-mete, and pseudo-para, in equal amounts. These dinitro compounds are shown to be precursors of a variety of other disubstituted OFF derivatives. Methods of characterization of isomeric disubstituted OFPs are extensively discussed, and the H-1 and F-19 NMR spectra of these derivatives are analyzed explicitly.
