Muhammad Hani Younes*

ABSTRACT

Condensation of the chalcones (1-9) with phenyl hydrazine produced the corresponding pyrazoline (10-19) by the of Michael reaction .All chalconeshave been synthesis by using Clasinen – Smidt reaction from reaction of 2-acetyl naphthalene and aromatic Aldehydes the structure of all products were elucidated by physical and spectroscopic methods. Using physical and spectroscopic methods such as I.R, U.V. and CHN elemental analysis.
