The interaction of 1-(3-cyano-5-nitropyridyl-2)pyridinium salts with different nucleophilic reagents yields 2-substituted 3-cyano-5-nitropyridine including 2-polyenamino derivatives. 3-Nitro-5(H)-5-iminodipyridol[1,2- a:3,2-c]pyrimidine hydrochloride is synthesized by the react of 2-chloro-3- cyano-5-nitropyridine with 2-aminopyridine.
CHEMISTRY OF ENOL ETHERS. LXXI. CONDENSATION OF THE TETRAETHYL ACETAL OF MALONIC ALDEHYDE WITH ENOL SILYL ETHERS

The action of trimethylsilyl ethers on the tetraethyl acetal of malonic aldehyde gave derivatives of 1,5- and 1,7-diketones and dialdehydes.The dialdehyde derivatives readily react with the hydrochloride salt of aniline in ethanol to form alkyl-substituted penta- and heptamethine salts.
