Asymmetric allylic amination or oxidation can be achieved by reaction of an alkene with a peroxycarbamate catalysed by a chiral copper bis-oxazoline complex, and the reaction can be tuned to give either the amination or oxidation product by reagent choice.

activation of C-O bonds in allylicalcohols by palladium complexes has been accelerated by carrying out the reactions in the presence of titanium(IV) isoproxide and 4 A molecular sieves. The acidic and less nucleophilic anilines such as diphenylamine, phenothiazine, 4-cyanoaniline, and nitroanilines are efficiently allylated under palladium catalysis using allylicalcohols as allylating reagents.
