- W2079040720 abstract "Die stufenweise Substitution der Chloratome in 1,3,5-Trichlor-2,4,6-tricyanbenzol durch N,N-Diphenylhydrazin führt zu 1-(N′,N′-diphenylhydrazino)3,5-dichlor-2,4,6-tricyanbenzol und 1,3-Bis-(N′,N′-diphenylhydrazino)5-chlor-2,4,6-tricyanbenzol. Aus 1,3,5-Triflour-2,4,6-tricyanbenzol erhält man 1,3,5-Tris-(N′,N′-diphenylhydrazino)2,4,6-tricyanbenzol. Oxidation der drei Hydrazinderivate ergibt die entsprechenden Mono-, Di- und Triradikale. 2,4,6-Tricyan-chlorbenzol und p-Dichlorteracyanbenzol lassen sich mit N,N-diphenylhydrazin zu N, N-Diphenyl-N′-(2,4,6-tricyanphenyl)bzw. N,N-diphenyl-N′-(p-chlor-tetracyanphenyl)hydrazin umsetzen. die Oxidation führt ebenfalls zu stabilen Radikalen. Chemische, spektroskopische und magnetische Eienschaften der Radikale werden beschrieben. The stepwise substitution of the chlorine atoms in 1,3,5-trichloro-2,4,6-tricyanobenzene by N,N-diphenylhydrazine leads to N,N-diphenyl-N′-(3,5-dichloro-2,4,6-tricyanophenyl)hydrazine and 1,3-bis(N′,N′-diphenylhydrazino)5-chloro-2,4,6-tricyanobenzene. From 1,3,5-trifluoro-2,4,6-tricyanobenzene Swe obtained 1,3,5-tris-(N′,N′-diphenylhydrazino)2,4,6-tricyanobenzene. Oxidation of the three hydrazine derivatives gives the corresponding mono, di, and tri radicals. The reaction of 2,4,6-tricyanochlorobenzene and of p-dichlorotetracyanobenzene yields N,N-diphenyl-N′-(2,4,6-tricyanophenyl)-hydrazine and N,N-diphenyl-N′-(p-chlorotetracyanophenyl)hydrazine, respectively. The oxidation of these products likewise leads to stable radicals. chemical, spectroscopic, and magnetic properties of the radicals are described and their stability is discussed." @default.
