Synthesis and characterization of new indeno[1,2-b]indole-co- benzothiadiazole-based π-conjugated ladder type polymers for bulk heterojunction polymer solar cells

We have developed a new ladder type, tetrafused, π-conjugated building block with indeno[1,2-b]indole (II) and extended the π-conjugation of the indeno[1,2-b]indole ring by incorporating a thiophene π-spacer in the 2nd and 8th positions to attain dithioph

Rearrangement of 3,3-Disubstituted 1-Aryl-4,5-dihydro-5-oxo-3H-1,2,4-triazolium Tetrafluoroborates; Part 2. A Convenient Synthesis of 1,5-Annulated 1,2-Dihydro-2-phenyl-3H-1,2,4-triazol-3-ones

1-Isocyanato-1-(phenylazo)cycloalkanes 3 react with tetrafluoroboric acid to yield 3-spiro substituted 4,5-dihydro-5-oxo-1-phenyl-3H-1,2,4-triazolium tetrafluoroborates 4.Compounds 4 rearrange with ring expansion in good yield to give, after basic workup,

Addition of Dimethyl Acetylenedicarboxylate to 1,2,3-Trisubstituted Indoles having no Hydrogen on the Carbon Atom attached to C-2.

Addition of dimethyl acetylenedicarboxylate to seven 1,2,3-trisubstituted indoles having no hydrogen on the carbon atom attached to C-2, has yielded fourteen adducts which are mainly fused γ-lactones, but which include a new phenanthridine-dione, a novel spiro-dihydroindole, and a carbazole formed by the loss of methane.All structures were elucidated by spectroscopy.
