A series of novel pyridine derivatives containing tetracyanobutadiene moiety (4-CN-TCPy) were obtained in good yields by the reaction of 2-chlorosubstituted pyridine-3,4-dicarbonitriles with malononitrile using Cs2CO3 as a catalyst.

[MediaObject not available: see fulltext.] The reaction of tetracyanoethylated 1,2-diarylethanones with morpholine was used for directed synthesis of spiro-fused diarylethenes, 8-amino-1-imino(oxo)-6-morpholino-2-oxa-7-azaspiro[4.4]nona-3,6,8-triene-9-carbonitriles. The intermediates in this process were tetracyanoalkanone salts. The formation of spiranes was sensitive to the nature of aromatic substituents at the carbonyl group of 3,4-diaryl-4-oxobutane-1,1,2,2-tetracarbonitriles. The obtained spiro-fused diarylethenes exhibited photochromic properties.
Rearrangement of 4-oxoalkane-1,1,2,2-tetracarbonitriles in the directed synthesis of aryl-substituted 2-(3-cyano-5-hydroxy-1,5-dihydro-2H-pyrrol-2-ylidene)malononitriles

[Figure not available: see fulltext.] 3-Aryl-4-oxoalkane-1,1,2,2-tetracarbonitriles were synthesized by the interaction of 2-aryl ketones with tetracyanoethylene. Directed rearrangement of them in acetic acid in the presence of ammonium acetate led to the
