Reaction of o-(aryloxy)phenylalkynes with electrophiles such as perchloric acid, tetrafluoroboric acid, benzenesulfenyl chloride, and iodine monochloride yielded dibenz[b,f]oxepine derivatives. Cyclization to the dibenz[b,f]oxepines competed with 1,2-addition of the electrophiles. The effect of substituents on the alkyne is also discussed.
