An efficient synthesis of arylidene acetophenones have been achieved by using the microwave heating in comparison to the conventional\r\nheating. In this work compound 1-phenyle-3-(4-droxyphenyle)-2-propen-1-one, 1-(4-chlorophenyle)-3-phenyle-2-propen-1-\r\none, and 1-(4-chlorophenyle)-3-(4-hydroxyphenyle)-2-propen-1-one have been synthesized by the condensation reaction between\r\naromatic aldehydes and substituted acetophenones under microwave irradiation.The compounds of aldehydes and acetophenones\r\nwere used as benzaldehyde, parahydroxybenzaldehyde, acetophenone, and parachloroacetophenone.Theresult shows that the time\r\ntaken for the reaction was reduced from the conventional 1-2 hours to 60ââ?¬â??120 seconds. The yield of the compounds in the conventional\r\nheating was moderate while the highest yield of 90ââ?¬â??98% was observed in MWI method. The structure of the compounds was\r\ncharacterized by their IR, 1H-NMR spectral data.
