✦ Synopsis

Aus o-Cyan-benzophenon und Formamid erhalt man neben 3-Formamino-I-0x0-3-phenylisoindolin (5) das rotviolette I-[3-Phenyl-isoindolyl-(l)-imino]-3-phenyl-lH-isoindol (I). 1 sowie an den Phenylkernen substituierte Analoga von 1 entstehen aus Phthalodinitrilen und Arylmagnesiumbromiden. Syntheses in the Heterocyclic Series, XVz) l-(3-Arylisoindol-l-ylimino)-3-aryl-lH-isoindoles o-Cyanobenzophenone reacts with formamide to give 3-formylamino-I-0x0-3-phenylisoindoline (5) and the redviolet 3-phenyl-l-(3-phenylisoindol-l -ylimino)-1 H-isoindole (1). Analogues of 1 substituted in the phenyl rings are obtained by treatment of phthalodinitriles with arylmagnesium bromides.

## Abstract Several 1,2‐disubstituted 3,6‐dioxo‐1,2,3,6‐tetrahydro‐pyridazines have been prepared. Direct alkylation of 1‐aryl‐3‐hydroxy‐6‐oxo‐1,6‐dihydro‐pyridazines with dialkyl sulfates is shown to give either 1‐aryl‐2‐alkyl‐3,6‐dioxo‐1,2,3,6‐tetrahydro‐pyridazines or a mixture of these with 1‐a
