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), (

## Abstract 1,6‐Dioxo‐cyclodeca‐3,8‐diene (4) and the __cis__ and __trans__ forms of 1,6‐diamino‐cyclodeca‐3,8‐diene (7) have been synthesized from naphthalene via isotetralin (1). No transannular reaction was observed during the reduction of the dioxime of (4) to the diamine (7).
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).

## Abstract The dynamic ^1^H and ^13^C NMR spectra of a series of mono‐ and bis‐annelated 4,9‐dihetero‐(__Z,Z__)‐cyclodeca‐1,6‐dienes were obtained and are discussed with respect to ground‐state conformers and the barriers to ring inversion, and to the restricted rotation about exocyclic partial C,
