Design, Synthesis, and Application of Phosphaalkenes to Unique Palladium and Gold Catalysts
摘要:
A 2-silyl-1,3-diphosphapropene was utilized as an asymmetrical P2 ligand of stable palladium(II) catalysts. Several phosphaalkene ligands were utilized for synthesis of novel gold(I) complexes which exhibited unique catalytic activity in 1,6-enyne cycloisomerization, indicating effects of P = C double bond, Au-Au contact, and sulfanyl group.
