cis-Bicyclo[6.1.0]nonatriene normally reacts with dienophiles as if it were the valence isomer, tricyclo[4,3,0,07,9]nona-2,4-diene, but with tetracyanoethylene and benzyne adducts are also obtained which are formally derived from cyclononatetraene, cis-Bicyclo[6.1.0]nonatriene is unreactive towards dienes, only products derived from cis-8,9-dihydroindene being obtained. A related addition of cyclopentadiene
