The compounds (E)-1,2-diphenyl-2-(phenylimino)ethanol, (E)-1,2-diphenyl-2- (p-tolylimino)ethanol, and (E)-2-((4-chlorophenyl)imino)-1,2-diphenylethanol) were synthesized by reaction of a p-substituted aniline with benzoin then oxidized with chromium trioxide-triethylamine in chloroform to give (E)-1,2-diphenyl-2-(phenylimino)ethanone, (E)-1,2-diphenyl-2-(p-tolylimino) ethanone, and (E)-2-((4-chlorophenyl)imino)-1,2-diphenylethanone in very high yield. The products were characterized by IR and NMR spectral analysis.

The reactions of ketones (benzophenone, 4-methylbenzophenone, acetophenone, acetone, and 2,2,4,4-tetramethyl-3-pentanone) and C-acylimines with dimethylcyanamide in the presence of titanium(IV) chloride were investigated. Benzophenone and 4-methylbenzophenone react with dimethylcyanamide to give 4,4-disubstituted 2-dimethylamino-3-aza-1-oxa-1,3-butadienes 5 and 4,4-disubstituted 2-dimethylanuno-1-N,N-dimethylcarbamoyl-1,3-diaza-1,3-butadienes 9. Ketones with enolizable hydrogen atoms undergo aldol reactions under these conditions. C-Acylimines 11b-11e, derived from benzil and substituted anilines, undergo [2 + 2] cycloaddition to dimethylcyanamide with subsequent ring opening to 1-(N,N-dimethylcarbamoyl)-2,3,4-triaryl-1,4-diaza-1,3-butadienes 15. 1,2-Diphenyl-2-(isopropylimino)ethanone (11a) reacts with dimethylcyanamide to give 2-dimethylamino-1-isopropyl-4,4-diphenyl-2-imidazolin-5-one (23) in a hitherto unknown multistep reaction. The structure of 23 was confirmed by an X-ray analysis. VCH Verlagsgesellschaft mbH, 1996.

The synthesis and characterization of substituted phenanthrene-9,10-quinone diimines of the type 9,10-bis(arylimino)-9,10-dihydrophenanthrene (aryl-BIP) is described. These rigid bisnitrogen ligands have been synthesized by a metal-mediated cyclodehydroge
Cyclization of Dianions from 2-Imino-1,2-diphenylethanone to Oxazolines, Oxazocines, and Oxazonines
Mehrotra, Kailash Nath,Singh, Indra Sen,Roy, Jalpana
, p. 2399 - 2402 (2007/10/02)
The reaction of 2-imino-1,2-diphenylethanone with sodium in ether and subsequent addition of carbon disulfide or ethyl chloroformate resulted in the formation of 3,4,5-trisubstituted 4-oxazoline-2-thiones and 2-ones, respectively. 1,4-Oxazonines and 1,4-o
Stereochemistry of Imino-group Reduction. Part 3. The Hydride Reduction of Achiral Benzil Monoimines
Alcaide, Benito,Lopez-Mardomingo, Carmen,Perez-Ossorio, Rafael,Plumet, Joaquin
, p. 1649 - 1654 (2007/10/02)
The RR,SS:RS,SR ratio of diastereoisomeric amino-alcohols obtained from the lithium aluminium hydride reduction of the monoimines prepared by reaction of benzil and various aliphatic and aromatic achiral amines has been determined.Stereochemical results a
