Substitution Reaction of Tetracyanoethylene with Acetone-Anils

Article abstract of DOI:10.1002/jccs.199600073

The products from the condensation of acetone-anils (1) and TCNE reaction were characterized after separation. The main products, tricyanoethylene derivatives (7-9) were isolated with the malonodinitrile derivatives (10-12), respectively. The [2+2] cycloaddition product (13), namely 5-methoxy-3,4-(2′,2′,3′,3′-tetracyanocyclobutano)-1,2- dihydro-2,2,4-trimethylquinoline also has been isolated. The distribution of these three products is substituent dependent.
