WebThe result is the formation of an allylic type radical. Since the SOMO in the allyl radical is an NBMO, this radical is easily reduced (by more solvated electrons) to the corresponding allylic anion. This anion is then protonated (by ammonia or an alcohol which has been added to the solvent) to yield 2-butene. http://websites.umich.edu/~chem461/Ex11.pdf

WebFig. 1.19. The coefficients, nodal properties and energies of the π MOs of an allyl system. The frontier orbitals of an allyl system depend on whether it is a cation, a radical or an anion. The number of π electrons in allyl cation, radical and anion is 2, 3 and 4, respectively. The frontier orbitals are given below: WebAllyl Radical (resonance description) Whenever two structures for a compound can be written but differ only in the positions of the electrons, the compound is a hybrid of both structures. Multiple possible resonance structures mean the compound is more stable than any single resonance structure would indicate. Allyl (propenyl) cation WebIt was found that the first excited state in the allyl radical correlates to the ground state of the cyclopropyl radical, confirming earlier qualitative predictions. No significant barrier was calculated for a conrotatory electrocyclization of A-state allyl radical to cyclo-propyl radical, explaining the short lifetime of the excited state. recover care heartland
