Abstract
When heated in refluxing benzene or tolune, alpha-diazo beta-ketophosp honates 2, prepared in three steps from aldeehydes or ketones, gave ri se to functionalized cyclobutenones 4 or phenolic compounds 5. These p roducts are formed by electrocyclisation respectively of a vinyl or di enylketene, resulting from a Wolff rearrangement.
