1,4-Dialkyl- and 1,4-diaryl-2,3-bis(hydroxyimino)butanes 7, from reduction of the corresponding 1,4-disubstituted 2,3-dinitro-1,3-butadienes 2, are transformed with satisfactory yields into 3,4-disubstituted 1,2,5-oxadiazole-2-oxide 5 and 4,5-disubstitute
ACTION DU CHLORURE D'ACETYLE ET DE L'ANHYDRIDE ACETIQUE SUR LE NITRONATE DE LITHIUM DERIVE DU PHENYL-2 NITROETHANE. REACTIVITE ELECTROPHILE OU DIPOLAIRE, EN FONCTION DU MILIEU, DE L'OXYDE DE NITRILE INTERMEDIAIREMENT FORME

The lithium nitronate salt derived from 2-phenyl nitroethane reacts with acetic anhydride and with acetyl chloride to give an intermediate nitrile oxide.Depending on the protonating character of the medium, this latter can react either as a 1,3 dipole to give the furoxan or, in the presence of a dipolarophile, the corresponding adduct; or as an electrophile leading to the chlorooxime or to derivatives of benzohydroxamic acid.The formation of the nitrile oxide, by loss of acetic acid from a nitronic-acetic mixed anhydride, appears to be the most plausible reaction pathway accounting for the above observations.

Some new aliphatic nitrile oxides have been prepared and allowed to react with pyridine or trimethylamine in ethanol: as for acetonitrile oxide, they undergo polymerization to cyclic oligomers or higher polymers.Linking of monomer units through C-O bonds
