Activation of a Cyclobutanone Carbon-Carbon Bond over an Aldehyde Carbon-Hydrogen Bond in the Rhodium-catalyzed Decarbonylation

摘要

A rhodium(I)-N-heterocyclic carbene complex achieved a high-yield decarbonylation reaction of cyclobutanones to selectively afford cyclopropanes.With this catalyst,a cyclobutanone having an aldehyde moiety underwent chemoselective decarbonylation of the ketonic carbonyl group with the aldehydic carbon-yl group left intact.
