Aryl-ONN-azoxy-?,?-dinitroalkanes and some of their derivatives
摘要:
Previously unknown N'-dinitroalkyl-NNO-azoxybenzenes have been prepared (by nitration of N'-(alpha-hydroximino)alkyl-NNO-azoxybenzenes) and transformed to some derivatives.
N?-(?-acetoximinoalkyl)diazene-N-oxides and some of their transformations
摘要:
Nitroso compounds of the aromatic and aliphatic series react with O-acetylalkanoylamidoximes in the presence of dibromoisocyanurate, forming the previously unknown N'-(alpha-acetoximinoalkyl)diazene-N-oxides, which under gaseous NH3 or oxalic acid in methanol lose the acetyl group and as a result are transformed into the previously unknown N'-(alpha-hydroximinoalkyl)diazene-N-oxides.
