合成了33个化合物Ph2P(CH2)nSiXYZ(n=1、2或3)和Me2P(CH2)2SiXYZ，其中X、Y或Z=H、Me、Ph或Cl，其方法是：(A)在四氢呋喃中，烷基(氯)硅烷与Ph2PCH_2Li·tmeda(n=1)或(b U.V.将氯代(乙烯基)硅烷或烯丙基(氯代)硅烷与Ph2Ph或Me2Ph(n=2或3)辐射，(C)将氯硅基产物还原为Si-H类似物。膦基烷基硅烷衍生物的表征包括全1H、13C和31P n.m.r。根据主链中亚甲基的数目n和Si上的取代基X、Y、Z的依赖关系讨论的数据，以及与相关化合物的比较。
Synthesis of thirty-three compounds Ph2P(CH2)nSiXYZ (n= 1, 2, or 3) and Me2P(CH2)2SiXYZ in which X, Y, or Z = H, Me, Ph, or Cl has been accomplished by (a) reaction at –78 °C in tetrahydrofuran between alkyl(chloro)silanes and Ph2PCH2Li·tmeda for n= 1, or (b u.v. irradiation of chloro(vinyl)silanes or allyl(chloro)silanes with Ph2PH or Me2PH for n= 2 or 3, with (c) reduction of the chlorosilyl products to Si–H analogues. Characterization of the phosphinoalkylsilane derivatives includes full 1H, 13C, and 31P n.m.r. data which are discussed in terms of dependence on the number of methylene groups, n, in the backbone and on the substituents, X, Y, Z, at Si, together with comparisons to related compounds.
