UV AND IR SPECTRA OF SOME ARENEDIAZOCYANIDES AND THEIR RADICAL-ANIONS

The UV and IR spectra of some arenediazocyanides and their radical-anions with the general formula p-X-C6H4N=NCN, where X=CH3O, CN, NO2, CNN=N, CNC6H4, NO2C6H4, CNN=NC6H4, NO2C6H4S, CNN=NC6H4O, CNN=NC6H4S, were studied.During radical formation long-wave absorption bands appear in the UV spectrum in the region of 600-700 nm.The frequencies of the absorption band for the nitrile group (Δν 80-95 cm-1) in the IR spectrum are shifted substantially.The integral intensities ACN increase by two orders of magnitude.The obtained experimental data show that during radical formation from the arenediazocyanides the additional electron is concentrated mainly at the diazocyanide group, and in the binuclear systems the effect of the anionic substituent N=NCN(1-) is not transmitted to the second benzene ring.It is suggested that the special features in the spectral characteristics of the arenediazocyanides and their radical-anions are due to the specific structural character of the azo group.

Reaction of 3-Aryl-1-(tetrazol-5'-yl)triazines with some Electrophiles: Mercury Derivatives and Fragmentations: A New Route to Aryl Diazocyanides

Treatment of 3-aryl-1-(tetrazol-5'-yl)triazines (4) with lead tetra-acetate resulted in a fragmentation to aryl-diazocyanides.The triazines (4) and their monomethyl derivatives when treated with mercuric acetate and phenylmercury hydroxide gave stable mer

OXIDATIVE FRAGMENTATION OF 3-ARYL-1-(TETRAZOL-5'-YL)TRIAZENES: A NEW ROUTE TO ARYL DIAZOCYANIDES.

Oxydation of 3-aryl-1-(tetrazol-5'-yl)triazenes with Pb(OAc)4 resulted in a fragmentation and gave aryldiazocyanides.

Phase-Transfer Synthesis of Arenediazocyanides and Synthesis of Arenediazosulfones from Arenediazonium Cations and the Formation of Reduced Pyridazines by 2 + 4 Cycloaddition Reactions

The remarkably versatile arenediazonium cations are also convenient to use and nondangerous when utilized as the BF4 or PF6 salts.Arenediazonium compounds have recently been shown to undergo the 2 + 4 Diels-Alder cycloaddition, but the reaction is solvent
