A facile microwave-assisted Knoevenagel condensation of various aldehydes and ketones using amine-functionalized metal organic frameworks

An amine-functionalized metal organic framework (MOF) was used as highly efficient and recyclable heterogeneous catalyst for Knoevenagel condensation of various aromatic aldehydes and ketones in ethanol. The catalytic efficiency was demonstrated by the hi

Novel bis-(3-cyano-2-pyridones) derivatives: synthesis and fluorescent properties

Abstract: Novel substituted bis-(3-cyano-2-pyridone) derivatives were prepared via a powerful method using enaminonitriles push–pull dienes as key building blocks. The synthesis was performed in three steps from easily accessible starting materials in goo

Amine-functionalized Metal-Organic Frameworks: An Efficient and Recyclable Heterogeneous Catalyst for the Knoevenagel Condensation Reaction

A highly efficient and reusable catalyst based on metal-organic frameworks (MOF) has been synthesized by post-functionalization and applied in Knoevenagel condensations of various aldehydes and ketones. The catalytic efficiency was demonstrated by the hig

Part 1: Synthesis and visible absorption spectra of some new monoazo dyes derived from ethyl 2-amino-4-(4′-substitutedphenyl)thiophenes

Series of monoazo dyes from some ethyl 2-amino-4-(4′- substitutedphenyl) thiophenes were prepared and characterized. The structure of the substances was confirmed by FT-IR, 1H NMR and mass spectroscopic techniques. The relationship among the structure of the dyes, their absorption characteristics and the solvatochromic and halochromic behaviors of the dyes were investigated. Introduction of electron-accepting substituent into the diazo moiety results in large bathochromic shifts in all solvents used. The dyes exhibited positive solvatochromism and their solvatochromic properties were discussed in relation to tautomerism.
