deactivating when attached directly to these sites. Fluorine at ortho-positions activates. These results enable a simple model, which accounts for orientation of nucleophilic aromatic substitution, to be extended to perfluoropolycyclic compounds.

Nucleophilic attack on octafluoronaphthalene gives a small amount of 1-substitution in addition to the predominant 2-substitution: methyl- lithium (8.4% 1-substitution), sodium methoxide (3.7%), diethylamine (0%), lithium diethylamide (4.8%).
