Semi-benzylic mechanism

If there are no enolizable hydrogens present, the classical Favorskii rearrangement is not possible. Instead, a semi-benzylic mechanism can lead to a rearrangement referred to as quasi-Favorskii. [Pg.217]

Stevens and coworkers reported on the quasi-Favorskii rearrangement of a norborane derivative. The exo-2-bromo-e /o-2-benzoyl norborane 52 tmdergoes a rearrangement with lithium anilide as the nucleophile to form 53. The concerted semi-benzylic mechanism of this reaction produces only one of the possible isomeric products. A trace amount of the bromo-displaced product 54 was also observed. The rearranged product was... [Pg.448]
