Condensation of chalcones with urea derivatives

Chalcones treated with a various metal ions & are cited to be highly reactive than ketone or aldehyde from which they are synthesized.This protocol has been displayed for the discovery of Fe (III) using 2 4-di-hydroxyChalcone givimg the attentiveness of intrusive ions reserved at a least 234 – TrihydroxyChalcone was applied as analytical substance for amperometric approximation of cooper and for spectrophotometric analysis of the Ge Singh and Bhardwaj presented 2-hydroxy-25 dichloro-4 methylbenzalacetophenone oxime as an analytical substances for Ni (II) Cu (II) and Pd(II).
