Abstract
|
|
|
|
The Knoevenagal reaction of malononitrile and acetylacetone gave the acyclic product 3 which was separated in a good yield and identified. The reactivity of 3 towards some chemical reagents is studied. Thus, the reaction of 3 with aromatic aidehydes, hydrazines and cyanomethylene derivatives gave products 6-12. Reaction of 3 with benzenediazonium chloride gave the primidine derivative 14.
