Abstract

Abstract1-Amino-3,5-diaryl-2,4,4,6,6-pentacyano-1-cyclohexenes are prepared by reaction of arylmethylenemalononitriles with malononitrile. The cyclohexene ring of (IVa) has a distorted N2-C1=C2-C7=N1 fragment. Steric effects in (IVa) cause a substantial increase in C6-C1 and C3-C4 bond length to 1.546(4) and 1.570(4) Å, respectively.

Synthesis of Aminophenylpolycarbonitriles from Arylidenemalononitriles by the Michael Reaction

The Michael Reaction can produce aminophenyldi- and tricarbonitriles from arylidenemalononitriles, with the dehydrocyanation step occurring in the aminohexenepolycarbonitriles.
