2,3-and 2,5-Dicyanobenzobarrelenes 5 and 6 have been synthesized and subjected to triplet-sensitized photoisomerization. 2,3-Dicyanobenzobarrelene 5 gave two di-p-methane rearrangement products 7 and 8 and a [2p+2p]-cycloaddition product 9. However, 2,5-dicyanobenzobarrelene 6 formed a single di-p-m
