The lack of azulene symmetry with respect to the axis perpendicular to a molecule creates
an asymmetry of the electronic system, increasing the charge density of the five-atom ring …

Rhodanine (R) is a heterocycle having complexing properties for heavy metal (HM) ions.
Considering the similar electron-donating character of diethylaminobenzene and azulene …

As a continuation of research on 1-vinylazulenes synthesis, on their physico–chemical
properties as well as on their use as colorimetric and electrochemical materials for the …

Azulene-based materials present very appealing properties for the preparation of advanced
materials. They can be irreversibly electrooxidated, leading to polymers, which can be …

This paper presents a new green protocol for Knoevenagel condensations of aldehydes and
compounds with an active methylene group in a binary mixture of ethanol/water (3: 7, v/v) …

Three (Z)-5-(azulen-1-ylmethylene)-2-thioxo-thiazolidin-4-ones are electrochemically
characterized by cyclic voltammetry, differential pulse voltammetry, and rotating disk …

We have developed the use of Bronsted acid for Knoevenagel condensation. Sulfated
polyborate has been used for efficient Knoevenagel condensation of aromatic, heterocyclic …

(E)-2-thioxo-5-((4, 6, 8-trimethylazulen-1-yl) methylene) thiazolidin-4-one (L) was
electrochemically characterized by cyclic voltammetry, differential pulse voltammetry and …

1, 3-Diiminoisoindoline (DII) and the closely related molecule, iminoisoindolinone are
important precursors in the synthesis of macrocycles and chelates such as phthalocyanines …

The electrochemical characterization of 2, 6-bis ((E)-2-(furan-2-yl) vinyl)-4-(5-isopropyl-3, 8-
dimethylazulen-1-yl) pyridine has been performed by cyclic voltammetry, differential pulse …
