A sterically bulky cyclic thiourea as an efficient ligand for palladium-catalyzed aerobic oxidation of alcohols
Sterically bulky N,N′-disubstituted cyclic thiourea ligand L1 has been demonstrated as an efficient ligand in palladium-catalyzed oxidation of alcohols using molecular oxygen as an oxidant. This new catalyst system has been applied to a wide variety of substrates such as benzylic alcohols, aliphatic secondary alcohols and allylic alcohols, producing the corresponding carbonyl compounds in good to excellent yields.

Dual chirality control of palladium(II) complexes bearing tropos biphenyl diamine ligands
Axial and center chirality of Pd complexes with tropos biphenyl secondary diamine ligands is shown to be controlled by chiral amide (R)-DABNTf, which can efficiently discriminate between two enantiomeric Pd complexes. The Royal Society of Chemistry 2005.
