Synthesis of 3-bromo flavones from 2-hydroxy-3, 5-dibromo-4'nitro dibenzoyl methane

A new 3-bromo substituted flavones have been synthesized by the reaction of 2-hydroxy-3, 5-dibromo-4'nitro dibenzoyl methane was dissolved in dimethyl formamide (DMF) and pure bromine was added. The mixture was refluxed for 1-3 hours. Then cooled, diluted

Syntheses of some New Heterocycles from 4'-Aminochromones. Part I

Syntheses of some new pyrazoles from hitherto unknown 4'-aminochromones have been described.Their structures have been confirmed on the basis of elemental analysis and spectral data.
