A study of the photochemistry of cis cis-cyclodeca-3,8-diem-1,6-dione (I) has recently -Ireported (1). We have been independently engaged in studying the photochemistry of I and present our results which differ significantly from those previously reported (1).

โฆ Synopsis
The photoohemical reaction of g&,EQS";yoloocta-lr5-diene (I) yielded the cross-bonded tricycle [3.3.0.02'6] octane (II) (1) and that of the cyclohexa-1,4-diene III led to the rearranged bicyclic product IV (2). We wish to report the p$toohemical reaction of the &&&-cyclodeca-1,6-diene system (3), ( ). This follows the Woodward-Hoffmann rule (5) for the photochemical
