A Simple and straightforward synthesis of cinnamic acids and ylidene malononitriles via knoevenagel condensation employing dabco as catalyst

Abstract

An efficient method for the synthesis of substituted cinnamic acid and ylidene malanonitriles is developed via Knoevenagel condensation of aromatic aldehydes with malonic acid and malononitrile in the presence of catalytic amounts of DABCO. This method has many advantages, such as mild reaction conditions, excellent yields, short reaction times and no furthur purification required.
