 Abstract    Einfache Synthesen der trimethylenverknüpften Triphosphine RP[(CH2)3PPh2]2 und ihrer Vorstufen Ph2P(CH2)3P(H)R (R Ph, Me) Oligophosphine Ligands, I Convenient Syntheses of the Trimethylene-linked Triphosphines RP[(CH2)3PPh2]2 and their Precursors Ph2P(CH2)3P(H)R (R = Ph, Me) The secondary-tertiary diphosphines Ph2P(CH2)3P(H)Ph (2) and Ph2P(CH2)3P(H)Me (3) have been prepared from Ph2P(CH2)3Cl (1) and NaP(H)Ph or LiP(H)Me, respectively. Metallation of 2 and 3 with n-butyl lithium and further reaction of the lithio-derivatives with one equivalent of 1 yields PhP[(CH2)3PPh2]2 (4) and MeP[(CH2)3PPh2]2 (5). The tritertiary phosphines 4 and 5 have likewise been obtained from RPLi2 (R = Ph, Me) and two equivalents of 1. The synthesis of 4 from PhPCl2 and two equivalents of the Grignard reagent of 1 is also reported. Each of the phosphines 1-5 was characterized by NMR and mass spectroscopy.
