Planar, Twisted, or Curved Extended Tetrathiafulvalenes with Polycyclic Aromatic Hydrocarbon Cores Featuring Five-Membered Rings. [PDF]
Chem Asian JTetrathiafulvalenes (TTFs) extended by polycyclic aromatic hydrocarbons (PAHs) constitute a class of redox‐active chromophores. This review summarizes PAH‐extended TTFs for which the PAH core features five‐membered rings together with six‐, seven‐, and/or eight‐membered rings.

SYNTHESIS OF 1,3-DITHIOLIUM SALTS CONTAINING N-METHYLPIPERAZINE
ACTA CHEMICA IASIThe synthesis of 4-aryl-2-(N-methylpiperazin-1-yl)-1,3-dithiol-2-ylium perchlorates has been accomplished by the acid catalyzed heterocyclocondensation of the corresponding substituted phenacyl N-methylpiperazin-1-carbodithioates. The later have been obtained from the reaction of various substituted -bromoacetophenones with a salt of N ...
