Abstract
This paper reports the results obtained in the Knoevenagel condensatio n between benzaldehyde and malononitrile using various alkaline and al kaline-earth carbonates as catalysts. Within each carbonate series, th e catalyst basicity increases with increasing ionic radius of the meta l. Also, the catalytic activity increases with increase in the solid b asicity.
