The treatment of phenylacetaldehydes in fluorosulfuric acid generates 2,3,6,7-dibenzo-9-oxabicyclonona-2,6-dienes.The generality of this reaction was tested on several derivatives which were substituted either at the 2-position or on the ring.Diastereoisomers, whenever obtained, were characterized by a combination of X-ray analysis and NMR data.Phenylacetone reacted differently and afforded the products of electrophilic aromatic substitution by fluorosulfuric acid.The structure of the unexpected minor reaction products was elucidated.
