Primary, secondary, and tertiary allylic nitro compounds underwent Pd (0)-catalyzed allylic substitution by stabilized carbanions, secondary amines, and benzenesulfinate ion (PhS02- ). a,@-Disubstituted a-nitro olefins also behaved as allylic nitro compounds, via base- catalyzed vinyl-allyl rearrangement, and underwent allylic substitution by secondary amines and PhS02-. The regiochemistry of these substitutions was dependent on the structure of ...
