    Secondary phosphane oxides R2P(O)H are most frequently used as preligands for phosphinous acid R2POH (R = alkyl, aryl) transition-metal complexes, which are very efficient catalysts for cross-coupling reactions. To investigate the influence of electron-deficient substituents on the catalytic activity, the coordination properties of bis(trifluoromethyl)-, bis(pentafluoroethyl)-, and bis[2,4-bis(tri

The different coordination properties of (C2F5)3P, (C2F5)2POH, (CF3)3P and (CF3)2POH were evaluated by complex formation with [Ni(CO)4]: the maximum achievable number of CO ligands substituted by (C2F5)3P is 1, by (C2F5)2POH is 2, by (CF3)3P is 3 and by the smallest ligand (CF3)2POH is 4.

    oxides were employed as preligands for the synthesis of catalytically active transition metal complexes of the phosphinous acids (CF3)2POH and (C2F5)2POH. Their reactions with solid PtCl2 and PdCl2 led to the formation of mononuclear phosphinous acid complexes [Cl2MP(Rf)2OH}2] (M = Pd, Pt; Rf = C2F5, CF3), which can be crystallized, for example, as its pyridinium salts, 2[HPy]+[Cl2PdP(CF3)2O}2]2–.

    Ring or chain? The two known phosphinous acids, (CF3)2POH and (C2F5)2POH, reveal hydrogen‐bridged aggregates in the solid state (see figure). The CF3 derivative forms helical chains, whereas the increased sterical demand of the C2F5 group leads to the formation of tetramers. The high catalytic activity of their palladium complexes (TON 24500) is highlighted in the field of cross‐coupling reactions
    环还是链?两种已知的次膦酸(CF 3)2 POH和(C 2 F 5)2 POH揭示了固态的氢桥聚集体(见图)。CF 3衍生物形成螺旋链,而C 2 F 5基团的增加的空间需求导致四聚体的形成。它们的钯配合物(TON 24500)的高催化活性在交叉偶联反应领域得到了强调。
