“…Intramolecular reductive coupling of the nitro groups to form the azo unit proceeds with notoriously low yields. The most frequently used procedure using Zn as the reducing agent in Ba(OH) 2 [12] or NaOH [13] gives irreproducible and low yields varying from 2% to not more than 19%. Glucose, however, in basic ethanolic solution turned out to furnish the azo compound 4 reproducibly in more than 20% yield.…”

“…This compound was acetylated (to give 6 ) and then nitrated to give 1,2‐bis(2‐nitro‐5‐acetamidophenyl)ethane ( 5 ). A two‐step oxidation protocol, adapted from that of Paudler and Zeiler,11 using Ba(OH) 2 , Zn, and HgO led to para ‐diacetamido‐substituted C 2 ‐bridged azobenzene 2 . Hydrolysis of the two acetamido groups of 2 with KOH resulted in para ‐diamino‐substituted C 2 ‐bridged azobenzene 4 , which was treated with chloroacetic anhydride/pyridine to give para ‐di(α‐chloroacetamido)‐substituted C 2 ‐bridged azobenzene 3 .…”

“…The photo-switchable molecule 5,6-dihydrodibenzo[c,g][1,2]diazocine (1) was synthesized according to published procedures. 42,43 For in situ sample irradiation, light emitted from high power LEDs (lumitronix) was directly coupled into the blunt and polished end of a 4 mm thick optical fiber (ceramoptec). At the tip of the fiber, the nylon jacket was removed and a pencil…”
