Metallkomplexe aus substituierten Glyoxalimin‐arylhydrazonen. α‐Arylhydrazono‐β‐imino‐butyronitrile und deren Nickelkomplexe

Abstract: P-Imino-a-arylhydrazono-butyronitrile (2) werden aus P-Amino-crotonsaurenitril und substit. Phenyldiazoniumsalzen synthetisiert. Die in guter Ausbeute erhaltenen Nickel(I1)-Komplexe (3) werden beschrieben und ihre Absorptionsmaxima mit denen der Liganden verglichen.Von den Formazanen l a l ) und den Malondialdehyddianilen l b 2 ) ist bekannt, daB sie ein chelierendes H-Atom enthalten und zur Komplexbildung mit Schwermetallen befahigt sind. Es war nun naheliegend, 1 so zu variieren, daR Y = N und X = C-CH3 ist.… Show more

“…2-Arylhydrazono-3-iminobutyronitriles were prepared by a literature method. 18 Preparation of 5-amino-4-arylazo-3-methylpyrazoles (1): General procedure A solution of 2-arylhydrazono-3-iminobutyronitrile (0.1 mol) and hydrazine hydrate (5.0 ml, 0.1 mol) in absolute ethanol (100 ml) was reduced pressure. The solid left was collected and recrystallised from the appropriate solvent to give the respective compound 1.…”
