Cyclopropyl aldehyde

WebCyclopropyl radicals react by hydrogen atom abstraction from the aldehyde and by combination with methyl radicals. About 10 % of the cyclopropyl radicals formed react by ring fission to form allyl radicals. These radicals undergo combination reactions with methyl radicals and, to a small extent, abstract hydrogen atoms from the aldehyde.
