T. Tsuji et al., TRICYCLO[4.2.2.2(2,5)]DODECA-1,3,5,7,9,11-HEXAENE - GENERATION AND CHEMICAL TRAPPING OF THE 3,4-DICYANO DERIVATIVE, Chemical communications, (22), 1997, pp. 2151-2152
The 3,4-dicyano derivative of hitherto unknown tricycle[4.2.2.2(2,5)]d
odeca-1,3,5,7,9,11-hexaene, in which six double bonds are uniquely arr
anged, is generated and chemically trapped with 1,2-dimethylenecyclope
ntane and tert-butyl-lithium.
