Thermal- and photo-induced transformations of N-aryl-N-nitrosohydroxylamine ammonium salts to azoxy compounds
摘要:
Heating of an ethanolic solution containing N-aryl-N-nitrosohydroxylamine ammonium salts at 78 degrees C produced the desired azoxy compounds in 80-93% yields. Furthermore, irradiation with UV light (lambda greater than or equal to 300 nm) of ethanolic solutions of those ammonium salts at room temperature also provided the desired story compounds in 51-72% yields.
