Closely related to the amidoximes are the nitrolic acids, R C(NO 2): NOH.
The proof of this was left for Hantzsch, who traced a connexion with the nitrolic acids of V.
The primary compounds form nitrolic acids of the type R C (: NOH) NO, the secondary yield pseudo-nitrols of the type RR': C(NO)(NO 2), whilst the tertiary nitro compounds are not acted upon by nitrous acid.
The nitrolic acids, R.
When heated with water and mineral acids, the nitrolic acids are completely decomposed, yielding fatty acids and nitrous oxide.
