Application of SiO 2 nanoparticles as an efficient catalyst to develop syntheses of perimidines and tetraketones

Abstract: In this paper, we explore the catalytic activity of SiO 2 nanoparticles (NPs) as an eco-friendly, efficient and reusable catalyst in the synthesis of 2,3-dihydro-1H-perimidines as well as tetraketones. For tetraketones syntheses, a si

CsF mediated rapid condensation of 1,3-cyclohexadione with aromatic aldehydes: Comparative study of conventional heating vs. ambient temperature

A mild, efficient and high yielding protocol for the synthesis of 2,2′-arylmethelene dicyclohexane-1,3-dione derivatives at room temperature and 9-aryl-1,8-dihydrooctahydroxanthene at conventional heating using cesium fluoride as a catalyst is reported. T

Synthesis of tetraketones in water and under catalyst-free conditions

A simple, environmentally friendly, tandem Knoevenagel condensation and Michael addition procedure is reported. The reactions between cyclic-13-diketones and a variety of aldehydes were carried out in water to afford tetraketones (64-99%). In this green synthetic protocol, the solvent water itself catalysed the reaction by hydrogen bonding, thus avoiding the use of any other catalysts to make the work up procedure easier.

9-(2-methylphenyl)-3,4,5,6,9,10-hexahydroxanthene-1,8(2H,7H)-dione

Several 9-(2-R phenyl)xanthenediones have been synthesized and the x-ray diffraction structure for the 2-methylphenyl derivative (4b) has been determined. This compound crystallizes in the monoclinic system, space group P21/n, with a = 11.729 (
