Smolinsky and Feuer have observed that treatment of 2-phenyl-1-azirine with aniline followed by mild acid hydrolysis gives mainly benzanilide, in addition to smaller amounts of 2,5-diphenylpyrazine and 3,4-dianilino-l, 2,5-triphenylpyrrole.86 These products have been rationalized as initially proceeding by nucleophilic attack of the amine at the imine carbon atom to give intermediate 154. No effort to isolate the 2-phenyl-2-anilinoaziridine (155) or (156) was made.

Nitrosamines derived from 5-amino-1,2,4-thiadiazoles are readily accessible stable compounds.3 Thermolysis of the substituted 5-nitrosoimino-1,2,4-thiadiazolines (48574 and 486383) produces the corresponding 5-ketones (487, 488) with evolution of nitrogen almost quantitatively. Their photolysis, involving n- n excitation, proceeds less uniformly. Irradiation of 486 in various solvents yields, as primary products, Hector s base (14b) and phenyl-cyanamide subsequent changes produce their 1 1-adduct, as well as 3,5-dianilino-l,2,4-thiadiazole, phenylurea, and other compounds, all in variable moderate yield. The photolytic fragmentation is more complex than that of comparable heterocyclic nitrosimines.384...

The outlined synthesis of 6,13-dichloroquinacridone 48 [50] (Scheme 18.20) resolved the conjecture [11]. Reaction of the disodium salt of the hydroquinone 44, generated by reduction of 2,5-dichloro-3,6-diethoxycarbonyl-l,4-benzoquinone 37, with N-phenyl-benzimidoyl chloride affords the dibenzimidate ester 45 that rearranges thermally [51, 52] to produce the N-aroyl diphenylamine 46 in excellent yield. Hydrolysis of the latter affords 2,5-dianilino-3,6-dichloroterephthalic acid 47.
