Nagalakshmi, K. published the artcileA simple and straightforward synthesis of cinnamic acids and ylidene malononitriles via Knoevenagel condensation employing DABCO as catalyst, Related Products of catalysis-chemistry, the publication is Asian Journal of Chemistry (2017), 29(7), 1561-1564, database is CAplus.
An efficient method for the synthesis of substituted cinnamic acids (E)-RHC:CHC(O)OH (R = 4-chlorophenyl, 2,6-dimethoxyphenyl, 3-nitrophenyl, furan-2-yl, etc.) and ylidene malanonitriles RC6H4HC:C(CN)2 is developed via Knoevenagel condensation of aromatic aldehydes such as furan-2-carbaldehyde, 2,3,4-trimethoxybenzaldehyde, 4-hydroxybenzaldehyde 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 further purification required.
