2-(3- indolyl) – 4,5 di phynyl imidazole.(IDPI) was used as a complexing agent in cloud point extraction for the first time and applied for selective pre-concentration of trace amounts of cadmium. The method is based on the extraction of cadmium at pH= 7.0 by using non-ionic surfactant Triton-X114 and 2-(3- indolyl) – 4,5 di phynyl imidazole. (IDPI) as a chelating agent. The adopted concentrati...

  Abstract A simple, sensitive and feasible cloud-point extraction (CPE) methodology has been developed for the separation and preconcentration of cadmium and lead ions in real samples. The metals in the aqueous solution were complexes with 2-(3- indolyl) - 4,5 di phynyl imidazole.(IDPI), at pH = 7.0 and Triton X-114 was added as surfactant. The variables effecting like concentration of Triton ...

A simple and efficient method for the synthesis of 3-indolyl-3-hydroxy oxindoles and unsymmetrical 3,3-di(indolyl)indolin-2-ones using microwave irradiation without catalyst and solvent is described. A series of 3-indolyl-3-hydroxy oxindoles and unsymmetrical 3,3-di(indolyl)indolin-2ones have been synthesized in very short reaction times of 5 and 10 minutes and in yields ranging from 31% to 98%...

The bicycloannulation reaction between cyclohexenone and indolyl enamines yields trans-3-(cyclic amino)-2-(3'-indolyl)bicyclo[2.2.2]octan-5-ones, and these adducts are conformationally restricted analogues of indolylethylamine (tryptamine) which exhibit structure-dependent affinity for the serotonin 5HT2 and 5HT1a receptors. The stereochemistry of the isomeric endo and exo adducts obtained is a...

Five new three-coordinate boron compounds with a B=N bond involving an indole or a substituted indole ligand including B(mesityl)2(indolyl), (1), B(mesityl)2(2-Me-indolyl), (2), B(mesityl)2(3-Me-indolyl), (3), B(mesityl)2 (7-Me-indolyl), (4), and B(mesityl)2(3-Ph-indolyl), (5) have been synthesized. The structures of these new compounds were determined by X-ray diffraction analyses. All five co...
