Abstract
:
Abstract: Organic synthesis in water is a new methodology of green chemistry. AlCl3-catalyzed diazocoupling of 1-(aryl/hetaryl)-3-phenyl-IH-pyrazol2-in-5-ones (1) in water with different aryl/hetaryldiazonium salts afforded the corresponding hetaryl-azopyrazolones (2) as colored products with high yields. These dyes were characterized by UV-vis, FIF-IR and H-1 NMR spectroscopic techniques and elemental analysis. Cotton, wool, silk and polyesters fabrics were dyed and their photostability and color fastness were identified. (c) 2005 Elsevier Ltd. All rights reserved.
