Ammonium salts, nitrogen-allylic substitution

Pd-catalyzed reactions of allylic esters such as aUyl acetates, carbonates, and phosphates with soft carbon nucleophiles such as malonate esters are useful for carbon-carbon bond formation (Sects. V.2.1.1-V.2.1.5). hi this section, Pd-catalyzed substitution reactions of nitrogen-containing allylic derivatives such as allylic amines, ammonium salts, tosylim-ides, and nitro compounds are described (Scheme 1). The allylic derivatives of other group 15 atoms have never been used as allyl unit source in Pd-catalyzed alkylation reactions so far.
