A cyclocondensation of TIPS-ethynyl-substituted diaminoarenes with in situ obtained 4,5-dibromocyclohexa-3,5-diene-1,2-dione has led to the synthesis of tetrabromotetraazapentacene (BrTAP). BrTAP is easily reduced to its air-stable radical anion and elect

The synthesis of novel (N?)acene-based cyclooligomers is reported. Glaser-Hay coupling of the bisethynylated monomers results in cyclodimers and cyclotrimers that are separable by column and gel-permeation chromatographies. For the diazatetracene, the use

The synthesis and characterization of nine isomerically defined S-arylmercapturic acids of interest in connection with the metabolism of the model hepatotoxin bromobenzene is described.Included are three S-(bromophenyl)-, two S-(bromohydroxyphenyl)-, and three S-(bromodihydroxyphenyl)mercapturic acids of defined substitution pattern.In addition, several related compounds with two or no bromine atoms are described.These syntheses depend on two basic methods, 1,4-addition of various arene thiols to acetamidoacrylic acid or the 1,4-addition of N-acetyl-L-cysteine to various benzoquinone derivatives.In addition, we describe a method for efficient conversion of the mercapturic acids to thioanisole derivatives, regioisomers of which can be separed and detected at low levels by capillary gas-liquid chromatography.
