(SYN- and ANTI-dinitriles), establish that the rearrangements occur with predominant, but not exclusive, inversion of configuration at the migrating center. Investigation of the interconversions of (SYN)- and ANTI-diesters and dinitriles reveal that racemic product is not obtained, as would be expected from an orthogonal-allylic diradical intermediate, but that the enantiomer corresponding to antarafacial
