Two new allyl complexes of palladium bearing the atropisomeric liganda 2-(diphenylphosphino)-2′-(dimethylamino)biphenyl (L1) and 2-(dicyclohexylphosphino)-2′-(dimethylamino)-biphenyl (L2) have been prepared and structurally characterized by X-ray crystallography. Their dynamic behavior as well as their structural characteristics in solution have been elucidated by the use of NMR techniques. Of particular interest, Pd-N bond rupture occurs with a low barrier ( 1 complex; however, this does not provide a facile pathway for atropisomerization of the ligand. A coordination mode involving η2 binding of carbon atoms in the (dimethylamino)phenyl moiety was also established for the dicyclo-hexylphosphino analogue L2.
