[reaction: see text] (3-Butenyl)cyclopropaneisomerizes thermally to norbornane and gives rise to many other products. Deuterium and carbon-13-labeled versions of (3-butenyl)cyclopropane have been prepared and isomerized, establishing that the formation of norbornane involves cleavage of the cyclopropyl C2-C3 bond.

The stereochemistry of reduction of mixtures of r-1-bromo-1-deuterio-c- and t-2-phenylcyclopropane and the cyclized products from 1,1-dibromo-2-(3-butenyl cyclopropane upon reduction with lithiumaluminumhydride give evidence of a configurationally equilibrated cyclopropyl radical as a reaction intermediate.
