Bridge-flipped' isomers may be defined as pairs of molecules related by a reversal of a bridge of atoms connecting two major parts of the individual molecules. This kind of isomerism is commonly found among benzylideneanilines and phenylhydrazones. Isostructural pairs...

In Vitro toxicity of 2- and 4-chloroaniline: comparisons with 4-amino-3-chlorophenol, 2-amino-5-chlorophenol and aminophenols.

Chloroanilines have been associated with renal and hepatic toxicity. This study (a) examined the in vitro hepatic and renal toxicity of 2-chloroaniline and 4-chloroaniline, (b) further examined whether aromatic ring hydroxylation would increase toxicity of the parent compound and...

Metabolism of 4-Chloronitrobenzene by the Yeast Rhodosporidium sp.

Applied and environmental microbiology

Corbett MD, Corbett BR.
PMID: 16345757
Appl Environ Microbiol. 1981 Apr;41(4):942-9. doi: 10.1128/aem.41.4.942-949.1981.

The yeast Rhodosporidium sp. metabolized 4-chloronitrobenzene by a reductive pathway to give 4-chloroacetanilide and 4-chloro-2-hydroxyacetanilide as the major final metabolites. The intermediate production of 4-chloronitrosobenzene, 4-chlorophenylhydroxylamine, and 4-chloroaniline was demonstrated by high-pressure liquid chromatography. Additional studies with selected metabolites...

A concise and efficient concurrent synthesis of 6,11-dihydrodibenzo[b,e]azepines and 5,6,11,12-tetrahydrodibenzo[b,f]azocines and their conversion to 4-oxo-8,13-dihydro-4H-benzo[5,6]azepino[3,2,1-ij]quinoline-5-carboxylates and N-acetyl-5,6,11,12-tetrahydrodibenzo[b,f]azocines: synthetic sequence, spectroscopic characterization and the structures of two products.

Reaction of 2-allyl-N-benzyl-4-fluoroaniline or 2-allyl-N-benzyl-4-chloroaniline with 98% sulfuric acid leads to the concurrent formation of halogeno-substituted 11-ethyl-6,11-dihydrodibenzo[b,e]azepines, (II), and halogeno-substituted 11-methyl-5,6,11,12-tetrahydrodibenzo[b,f]azocines, (III), in each case in (II):(III) molar ratios of ca 2:1. Further reaction of (II) leads to ethyl...
