Abstract

The synthesis of a series of symmetrical and unsymmetrical tripodal tetradentate alkylphosphine ligands is described. Me ₂PCH ₂CH ₂P(CH ₂CH ₂CH ₂PMe ₂) ₂ was synthesized by the photochemical reaction of (2-(dimethylphosphino)-ethyl)phosphine with excess allyldimethylphosphine, and Me ₂PCH ₂CH ₂CH ₂P(CH ₂CH ₂PMe ₂) ₂ was synthesized by the photochemical reaction of (3-(dimethylphosphino)propyl)phosphine with excess dimethylvinylphosphine. The known ligand P(CH ₂CH ₂PMe ₂) ₃ was synthesized in a one-step reaction by the photochemical addition of dimethylphosphine (3 equiv) to trivinylphosphine. The tetradentate ligands form one-to-one complexes Fe(PP ₃)Cl ₂ with iron by displacement of weaker phosphine ligands.
