Nitrosoalkane dimers react with acid halides to yield α-halogeno-azoxy compounds with the substituent α to the oxygen-bearing nitrogen. In the presence of silver carbonate, the corresponding α-acyloxy-azoxy compounds are formed.
A reaction of N,N-disubstituted hydrazones (1) with bases has been investigated. N - Methyl - N -tosylhydrazones of aliphatic carbonyl compounds have been shown to combine with primary and some secondary aliphatic amines to form α-aminodialkyldiazenes (2) hitherto unknown, and with triethylamine and alcoholic solutions of alkalies to form symmetric azines (10). Some structural factors contributing
