Facile and specific nickel-catalyzed de-N-allylation
摘要:
A general procedure for a chemoselective removal of the allyl (2-propenyl) functionality on basic, neutral and acidic nitrogens by diisobutylaluminum hydride or trimethylaluminum in the presence of a catalytic amount of (dppp)NiCl2 has been developed.

Nickel(0)-catalyzed direct N-allylation of amides and p-toluenesulfonamide with allylic alcohols took place in the presence of Ni0–diphosphine complexes. The corresponding N-allylated (and/or N,N-diallylated) products were obtained in moderate to high yields under neutral conditions.
