stereochemistry of the reaction depends on the ring size of the substrate and on the structure of the alcohol, and is syn predominant in the case of fluorination of five-, anti predominant in six-, and slightly to nearly exclusively syn predominant in seven-membered ring benzocycloalkene analogues. The relativerates measured for methoxy-fluorinations of a set of seven phenyl-substituted alkenes with

while equal amounts of both diastereoisomers were formed in the case of (E)-1-phenyl-1-propene and acenaphthylene. In the phenyl-substituted benzocyclene series the stereochemistry of fluoro-alkoxylation was found to be dependent on ring size and on the structure of the alcohol. The resulting vicinal fluoroalkoxy adducts were transformed by heating in aqueous HBr to 2-fluoro-1-phenylbenzocyclenes. Correlation
