Tricyclo[4.2.2.22,5]dodeca-1,3,5,7,9,11-hexaene: generation and chemical trapping of the 3,4-dicyano derivative

Abstract

The 3,4-dicyano derivative of hitherto unknown tricyclo[4.2.2.22,5]dodeca-1,3,5,7,9,11-hexaene, in which six double bonds are uniquely arranged, is generated and chemically trapped with 1,2-dimethylenecyclopentane and tert-butyllithium.
