Malonic ester syntheses Malononitrile

Cyclocondensation of o-hydroxybenzaldehydes with reactive methylene compounds (malonic ester, cyanoacetic ester, malononitrile) in the presence of piperidine and other bases (Knoevenagel synthesis) ... [Pg.250]

Selenophene-2-aldehyde takes part in the Hantzsch synthesis [Eq. (I)]108 and reacts readily with ammonia, aromatic amines and diamines,109 hippuric, barbituric, and malonic acids, malononitrile,70 and rhodanine.109 /3-(Selenien-2-yl)acrylic acid has been obtained from selenophene-2-aldehyde by the Perkin reaction and by Knoevenagel condensation with malonic acid.70 Esters of /9-(selenien-2-yl)acrylic acid are easily formed by condensation of the aldehyde... [Pg.31]
