The Bamford-Stevens reaction of 2-vinylcyclobutanone tosylhydrazone sodium salt (13) has been studied with respect to the potential carbene-carbene rearrangement 3 -> 4. 2-Vinylcyclobutylidene (3) surprisingly undergoes exlusively carbene rearrangements.In 3 the cyclobutylidene-methylenecyclopropane rearrangements to 16 and 17 dominate.The 1,3-carbon migration of the divalent carbon is not observed.
