- W68002067 abstract "The potential of domestic microwave oven has been utilized to accelerate the reactions of 2-aryl-3-(3 aryl-3-oxo-propen-I-yl)-indoles (III) with hydrazine hydrate/phenyl hydrazine and thiourea, to obtain 2 aryl-3-[3-aryl-pyrazol-5-yl]-indoles (IV) and 2-aryl-3-[4-aryl-5, 6-dihydro-2(l H)-thioxopyrimidine-6 yl]-indole (V). The former indolyl chacones (III) have been synthesized by the condensation of 2-aryl IH-indole-3-carboxaldehyde (I) and fluorinated acetophenones (II) in the presence of sodium hydroxide in open borosil glass vessels under microwave irradiation, using ethanol as energy transfer medium. The results obtained demonstrate the versatility of the process as considerable reaction rate enhancement has been observed bringing down the reaction time from hours to seconds, along with improved yields. All synthesized compounds have been characterized on the basis of elemental analyses, IR, IH NMR, 19F NMR and mass spectral studies." @default.
