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.

The reaction of 1-trimethylsilyloxy-1-alkenes and 1-trimethylsilyloxy-1,3-butadienes with an aminoformylating complex and subsequent treatment by aniline hydrochloride gave tri- and pentamethine salts, namely, the hydrochloride salts of the dianils of malonic and glutaconic aldehydes.

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.
REACTIONS OF PERCHLORO-2-CYCLOPENTEN-1-ONE AND PERCHLORO-4-CYCLPENTENE-1,3-DIONE WITH PYRIDINE AND QUINOLINE DERIVATIVES

By the reaction of perchloro-2-cyclopenten-1-one with pyridine and quinoline derivatives the corresponding onium salts of 2,4,4,5,5-pentachloro-3-hydroxy-2-cyclopentenone were obtained.The analogous reactions of perchloro-4-cyclopentene-1,3-dione lead either to onium salts of 2,2,5-trichloro-4-hydroxy-4-cyclopentene-1,3-dione or to betaines.The effect of the nature of the solvent and the structure of the amine on the reaction path was examined.
