Bicyclo[4.1.0]hept-2-ene is readily transformed stereospecifically and regiospecifically via Pt(H) to trans-disubstituted cyclohexane and cyclohexene derivatives. A Pt(II) intermediate has been isolated.

The occurrence of a structurally degenerateCoperearrangement which proceeds rapidly at room temperature is revealed by the examination, at varying temperatures, of the N.M.R. 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
