Two chalcone derivatives have been synthesized from 4-hydroxybenzaldehyde with 1-acetylnaphthalene using KOH 6 N catalyst by aldol condensation using microwave iradiation and 4-hydroxybenzaldehyde with 2-acetylnaphthalene using SOCl2 catalyst using stiring method. Synthesis result have been obtained two compounds, (E)-3-(4-hydroxyphenyl)-1-(naphthalene-1-il)prop-2-en-1-on (CR1) and (E)-3-(4-hyd…
