This article reviews the complexation properties of various bis-porphyrins, linked by either flexible or rigid spacers. The fascinating supramolecular architectures obtained by complexation of bis-porphyrins feature specific structural, physico-chemical, supramolecular and photophysical properties, with an array of potential applications in material chemistry.

Pyridazin-3(2H)-ones are inexpensive, stable, and easily prepared heterocycles. Since pyridazin-3(2H)-ones readily form stable anions, and can act as good leaving group. Their utility as synthetic auxiliaries was recently demonstrated by Yoon’s group. 2- Substituted-pyridazin-3(2H)-ones are also useful both the electrophilic agents and equivalents for the functionalization of the electron rich compounds and active methylenes, and Read More

C-glycosylflavonoids represent a group of oxygen heterocyclic compounds found widespread in a variety of plants. Synthetic organic chemists are now progressively utilizing C-glycosylflavonoid scaffolds due to their high biological potential. The present review deals with advances in C-glycosylflavonoids research, namely establishing a new updated database of the natural occurrence of Cglycosylflavonoids - one hundre Read More

In view of the unique properties, like high solubility in most of the organic solvents, poor complexing ability, low charge density, stability under mild conditions and high electronegativity, transition metal perchlorates have been found to be highly effective catalysts/ reagents in wide variety of functional group transformations leading to the synthesis of large number of important organic compounds. This review presents the re Read More

This review summarizes research results concerning the reactions of phosphonyl carbanions with different carbon-nitrogen systems, amines, amides, imines, oximes, hydrazones, nitriles, diazo compounds, isocyanates, and azides, reported by us and other research group over the last years. It outlines the utility of such reactions in various aspects of heterocyclic chemistry. Some of these reactions have been applied su Read More

The present report is concerned with the designing, obtaining and characterization of novel light –sensitive molecules, belonging to second generation meso-tetraarylporphyrin derivatives. A new structure of A3B porphyrin, namely: 5-(4-pyridyl)-10,15,20-tris(4- phenoxyphenyl)-porphyrin was synthesized in fair yield by multicomponent reaction and characterized by 1H-NMR, FT-IR, UV-vis, fluorescence, MS, HPLC, TLC, AFM Read More

RuCl3·3H2O was found to be an effective catalyst for one-pot reactions of benzylic alcoholes with indoles affording the corresponding bis(indolyl)methanes under air atmosphere at room temperature in moderate to excellent yields. It is noteworthy that the RuCl3·3H2O system displayed a preference for the primary versus secondary benzylic group of a benzylic diol in intramolecular competition experiments.
