Cyclopropyl aldehyde
WebAldehydes, cyclopropyl => conjugated The 1-alkoxycyclopropyllithiums 136 and 140 have been added to a variety of conjugated aldehydesand ketones to produce cyclopropyl … 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.
