BOX 19395-4697 Tehran, Iran Journal Article 2015 09 05 In this paper, new (2E, 2'E)-3, 3'-(((3- hydroxypropane-1, 2-diyl) bis (oxy)) bis (2, 1-phenylene)) bis (1-phenylprop-2-en-1-one) (2a) was prepared in good yield by condensation reaction of acetophenone with bisaldehyde (1a) in ethanolic NaOH solutions at room temperature. The (2E, 2'E)-3, 3'-(((3- hydroxypropane-1, 2-diyl) bis (oxy)) bis (2, 1-phenylene)) bis (1-phenylprop-2-en-1-one) (2a) was immediately reacted with phenyl hydrazine under refluxing conditions in the presence of potassium hydroxide to obtain the corresponding 2, 3-bis (2-(1, 3-diphenyl-4, 5-dihydro-1H-pyrazol-5-yl) phenoxy) propan-1-ol (3a). The newly synthesized compounds confirmed by melting point and TLC and their structure were established by various analytical techniques such as IR, 1H-NMR, 13C-NMR and elemental analysis. https://icc.journals.pnu.ac.ir/article_2250_5ee93fad306b4de766e0329144ec5ca4.pdf
