Nickel acetylacetonate effectively catalyses the carbon-carbon bond formation between malononitrile and P-dicarbonyls. In these metal-catalysed reactions malononitrile behaves as an electrophile towards the intercarbonylic carbon, so exhibiting a reverse reactivity compared with that one under basic
The reactions of 1,2-diaminobenzimidazoles with 13dicarbonyl compounds give 1,2,4-triazepino [2,3\_a]benzimidazole and pyrimido [1,2-a] b enzimidazole-derivatives.
Tetranethoxyethylene (TIIE) is a highly nucleophilic alkene that reacts with methanol, malononitrile or benmic acid to give the addition products, pentaoethoxyethane, 1,2,2~trimethoxyethyltdenemalononitrile and 1,1,2,2-tetramethoxyethyl benxoate respectively'. Roreover, the last product decomposes t
