ChemInform Abstract: Radical Cation Cope Rearrangement of 1,5-Hexadiyne to 1,2,4,5-Hexatetraene (Bis(allene)) at 77 K.
Abstract
Radiolytic oxidation of the title compounds (I) and (III) results in just the same ESR spectrum.
ChemInform Abstract
Radiolytic oxidation of the title compounds (I) and (III) results in just the same ESR spectrum. So the generation of radical cation (II) from (I) by Cope rearrangement is demonstrated. The ESR assignment is further corroborated by the finding that this ESR spectrum grows in with high intensity upon the photolysis of the radical cation from (IV) with visible light.
