description

Abstract The mechanism of the reaction of allyl complexes [Pd(η3-2-R′C3H4)(NN′)]+ (NN′ = α-diimine ligand) wiht BPh4− in the presence of activated olefins (ol), yielding the products [Pd(η2-ol)(NN′)] and PhCH2C(R′)CH2, has been investigated. The results are interpreted in terms of extensive association between the cationic substrate and the BPh4− anion in a tight ion-pair, followed by rate-determining phenyl transfer to the palladium center and fast reductive elimination of allylbenzene.
