Abstract

The occurrence of a structurally degenerate Cope rearrangement which proceeds rapidly at room temperature is revealed by the examination, at varying temperatures, of the NMR spectrum of bicyclo [5.1. 0] octa-2, 5-diene (I). This molecule is made by the cyclopropanation of cycloheptatriene in the 3, 4 position according to Gaspar-Roth. Its structure is assigned by virtue of its conversion to bicyclo [5.1. 0] octane on catalytic ...
