Synthesis, Structure, and 2D‐NMR Studies of Novel Chiral (η³‐Allyl)palladium(II) Complexes Containing the Bidentate Ligand Sparteine

In situ enzymatic screening (ISES) of P,N-ligands for Ni(0)-mediated asymmetric intramolecular allylic amination

“…14 Later, Togni et al showed that sparteine indeed displays bidentate coordination in a π-allyl-Pd complex. 15 Finally, the recent successes with sparteine as a chiral element in the Pd(II)-mediated oxidative kinetic resolution of secondary alcohols that have been registered by the groups of Sigman et al 16 and Stoltz et al 17 suggest that renewed attention should be paid to this chiral ligand for late transition metal chemistry.…”

Steric Effects in Enantioselective Allylic Alkylation Catalysed by Cationic(η3‐Allyl)palladium Complexes Bearing Chiral Pyridine‐Aziridine Ligands

“…[16] Hence, it appears that the aziridine nitrogen generally forms a shorter bond a with palladium cation than other sp 3 -hybridised nitrogen atoms.…”

Palladium-Catalyzed Hydroarylation of 1,3-Dienes with Boronic Esters via Reductive Formation of π-Allyl Palladium Intermediates under Oxidative Conditions

“…This catalyst system performs poorly with little conversion of the substrate which may be due to the excellent stability of N-heterocyclic carbene allyl palladium species 8. Therefore, we explored the use of Pd[( − )-sparteine]Cl 2 , whose π-allyl complexes have been previously structurally characterized and successfully used in nucleophilic addition chemistry 9. The use of this catalyst leads to a significant improvement in conversion and GC yield of the desired product.…”
