Regiochemical control in reductive elimination of (η3-crotyl)(aryl)palladium(II) complexes
摘要:
The electronic character of PR3 ligand controls the relative rates of the geometrical isomerisation and the cis reductive elimination of η3-crotyl(aryl)palladium compelxes; more electron-withdrawing phosphites lead to selective bond formation at the more substituted allyl end.

Allylic electrophiles used in Pd-catalysed allysic alkylation greatly accelerate reductiveelimination of η3-allyl(organo)palladium(II) complexes, via a PdIV intermediate, to give the coupling products and η3-allylpalladium(II) salts.
