Abstract


The reaction of tetracyanoethylated 1,2-diarylethanones with morpholine was used for directed synthesis of spiro-fused diarylethenes, 8amino-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 3,4diaryl-4-oxobutane-1,1,2,2-tetracarbonitriles. The obtained spiro-fused diarylethenes exhibited photochromic properties.
