Acetonitrile phenylhydrazone

Phenylhydrazones 51a and 51b have been converted into 1,2,4,5-dihydrotetrazines 52a and 52b by reflux in acetonitrile in the presence of ammonium acetate <00S1166>. 

Oxidation of ketone phenylhydrazones generates a radical-cation centre on the nitrogen atom adjacent to the benzene ring. The radical-cation is delocalised by both the hydrazone group and the phenyl ring. Reactions of 1,3,5-triphenyl-A -pyazolines illustrate the properties of these radical-cations. Two one-electron waves are seen at a rotating disc electrode in acetonitrile and for 1,3.5-triphenyl-pyrazoline, Ey. = 0.82 and 1.68 V vs. see [33]. The delocalised radical-cation is...

Ogawa and Fritz (1985) developed a method for the identification of acrolein in water. A known volume of water is passed over a column of zeolite that traps the acrolein. The column is then eluted with acetonitrile, and derivatization using DNP follows. By following this procedure, a sample that can be analyzed by HPLC is obtained. Other derivatizing agents that have been used successfully for the monitoring of acrolein in the environment include dimedon, phenylhydrazone, 4-hexylresorcinol, and 3-methyl-2-benzothiazolone (Altshuller and McPherson 1963 Peltonen et al. 1984). 

CCI4 added to a stirred suspension of N -benzoyl-N-phenylhydrazine and tri-phenylphosphine in acetonitrile, and the product isolated after 20 hrs. a-chloro-benzaldehyde phenylhydrazone. Y 64%. F. e. s. P. Wolkoff, Can. J. Chem. 55, 1333 (1975). 

The study of the interaction between WOF4 and phenylhydrazone of acetone in acetonitrile showed [69] that the reaction proceeds similarly to the case with simple oximes [9,57,46], ketimines [39], and secondary amines [14,70],...
