  A series of unsymmetrical 1,2-bis(phosphino)ethanes R2PCH2CH2PR′2 (2a–d) and 1-arsino-2-phosphinoethanes R2AsCH2CH2PR′2 (3a–c) mainly with bulky substituents R and R′ were prepared from the cyclic sulfate 1 by stepwise cleavage of the carbon–oxygen bonds by LiPR2 and LiPR′2 or LiAsR2 and LiPR′2, respectively. Analogously, racemic mixtures of R2PCH2CH(Me)PPh2 (R = iPr 5a, Cy 5b) as well as the enantiomers (R)-5a, (R)-5b and (R)-tBu2PCH2CH(Me)PPh2 (R)-5c were obtained from the corresponding unsymmetrical cyclic sulfates 4 and (S)-4. On a similar route, the racemates of the 1,3-bis(phosphino)propanes R2PCH2CH2CH(Me)PPh2 (R = iPr 7, tBu 8), optically pure (R)-8 and (S,S)-iPr2PCH(Me)CH2CH(Me)PPh2 (S,S)-10 were prepared. The reaction of [RhCl(η4-C8H12)}2] with chelating ligands L–L, where L–L is R2PCH2P(men)2 (R = iPr, Ph; men = (1S,2R,5S)-menthyl), Cy2AsCH2P(men)2, or (R)-5a, (R)-5b, (R)-5c, (R)-8 and (S,S)-10, in the presence of AgPF6, gave the complexes [Rh(η4-C8H12)(L–L)]PF6 (12a–h) which were used as pre-catalysts in the hydrogenation of the methyl ester of α-acetamidocinnamic acid (ACM). Depending on L–L, the solvent, the temperature and the pressure of H2, optical yields of up to 69% ee were achieved. For two of the rhodium complexes, 12c and 12d, the molecular structures were determined by X-ray crystallography.

  Abstract Cobalt arsenide and phosphide thin films were prepared by organometallic chemical vapour deposition (OMCVD) at deposition temperatures between 300 and 500°C in a hot-wall reactor using a two-source method and a single-source method. The combination of tricarbonylnitrosylcobalt (-I) and di- t -butylphosphine or di- t -butylarsine was employed as a two-source method. The known hexacarbonyldicobalt

  摘要在热壁反应器中，采用两源法和单源法，通过在300至500°C的沉积温度下，通过有机金属化学气相沉积（OMCVD）来制备砷化钴和磷化钴薄膜。三羰基亚硝酰基钴（-I）和二叔丁基膦或二叔丁基ar的组合用作两种来源的方法。已知的六羰基二钴簇，CO 2（CO）6（μ-E2）（E = P，As），和取代的二羰基亚硝酰基钴络合物，Co（CO）2 [E（t Bu）2 H]（NO）（E = P，As）被用作单一来源的前体。俄歇电子能谱表明，大多数薄膜中的Co：P和Co：As比率接近于1，只有少量杂质，例如碳和氧。薄膜在室温下的电阻率对于磷化钴为450至1140μΩ-cm，对于砷化钴为115至1140μΩ-cm。X射线衍射分析表明砷化钴膜是多晶的，而磷化钴膜的范围从无定形到多晶。通过场发射扫描电子显微镜测得的膜的晶粒尺寸为150至2000A。对于单源方法，膜生长速率为4至30 A min -1，对于双源方法，膜生长速率为150至330
