✦ Synopsis

The photolysis of bis aryl-1,3 triazenes carried out in non-aromatic solvents gives products whose structures are consistent with a cage recombination process of homolytically formed radicals and the subsequent abstraction of hydrogen from the solvent molecules by these arylamino radicals.

In aromatic solvents, a free-radical chain process leads to the formation of products resulting from the homolytic substitution on the solvent.

Previous attempts to observe a reversible cis-trans photoisomerisation on the -triazenes as in azobenzenes have been unsuccessfull.

## Abstract The reaction of the 4,4‐dialkylated 2‐cyclohexenones **1** or **2** with a twofold excess of a secondary amine **3** affords the 2‐amino‐1,3‐cyclohexadienes **4** and **5**, respectively. Irradiation (λ ≧ 300 nm) of the morpholino derivative **4a** yields a mixture of the isomeric 3‐mor
