  Synthesis and properties of diethyl 5,10-dihetera-5,10-dihydroindeno[2,1-a]indene-2,7-dicarboxylates

  摘要：

  A series of six heterocyclic diesters lb-6b containing all combinations of nitrogen, sulfur, and selenium has been prepared from a common precursor, diethyl 2,2'-dinitrostilbene-4,4'-dicarboxylate. Electrochemical analysis showed oxidation potential increases in the order N < Se < S, and the same trend was observed for maxima of UV absorbance. Electrochemical oxidation of indoloindole lb (but not the other members of the series) generates a persistent radical cation whose properties were investigated. Diesters containing sulfur and selenium (but not nitrogen) form S(A) liquid crystals. A new synthetic method leading to the indolo[1,2-b]indazole ring system has been found.
