摘要：Air-stable P,N-bidentate ligands L1-L7 with cyclic secondary amine moieties linked to the benzene rings of triphenylphosphine were designed and prepared. The chelating coordination mode of the P, N-bidentate ligands to the Pd(II) center was confirmed by determining the X-ray structures of the Pd(II) complexes C1 and C2 derived from ligands L1 and L2, respectively. The ligands were used for the selective synthesis of delta-lactone through the palladium (Pd)-catalyzed telomerization of 1,3-butadiene with carbon dioxide. The highest yield (60% with 79% selectivity) was observed using the Pd-2(dba)(3)/4(2-(diphenylphosphino)phenyl)morpholine (L2) catalyst system. (C) 2011 Elsevier B.V. All rights reserved.
