Cyclopropyllithium compounds, produced by the metallation of 1,1-dicyclopropyl- and 1-methyl-1-cyclopropylmethylenecyclopropanes with the butyllithium-tetramethylethylenediamine complex, undergo thermal rearrangement and give, after treatment of the reaction mixture with water, spirohept-4-enes.A possible rearrangement scheme is proposed and discussed.
