A Rapid and Highly Effectual Protocol for the Synthesis of Bis-coumarins using Triethylaminium-N-sulfonic Acid Tetrachloroaluminate under Solvent-Free Conditions
Journal Title: Chemical Methodologies - Year 2019, Vol 3, Issue 0
Abstract
In this work, a rapid and highly effectual protocol for the synthesis of bis-coumarins has been developed. The one-pot quasi three-component reaction of aromatic aldehydes (1 eq.) with 4-hydroxycoumarin (2 eq.) in the presence of catalytic amount of protic acidic ionic liquid triethylaminium-N-sulfonic acid tetrachloroaluminate (TSAT) under solvent-free conditions afforded the mentioned compounds in high yields and short reaction times.

Cyclic Voltammetry for the Interaction between Bismuth Nitrate and Methyl Red in Potassium Nitrate Solutions
Cyclic Voltammetry of bismuth nitrate (BN) using different concentrations was practically measured by the use of DY2000 potenstiostat. We used 0.1 M KNO3 as a transporting medium for the diffusion of the ions used as the...
