  摘要：

  制备了一系列 RhI 复合物并用以下半稳定性两亲性膦进行表征：R-(C6H4)-(OCH2CH2)n-PPh2 [1 (R = 叔辛基，n = 1), 2 (R = 叔辛基， = 5), 3 (R = 叔辛基, = 13), 4 (R = 正壬基, = 1.4), 5 (R = 正壬基, = 5), 6 (R = 正壬基, = 11 )]。1-6 与[Rh(COD)(THF)2]+ 之间的反应以及随后与CO 的反应通过31P NMR 和IR 光谱进行了研究。数据与配体 2-6 的 P 配位和螯合（P，O）物质的形成一致，与这些配体的半稳定性特征一致。在配体 1 的情况下，已分离出复杂的反式-[Rh(1)2(CO)2]+，并已检测到顺式-[Rh(1)2(CO)2]+ 化合物。[Rh(1)2(CO)]+ 是通过反式-[Rh(1)2(CO)2]+ 脱羰制备的，和低温 NMR 光谱研究表明 1 具有非常弱的

  4-tetramethylbutyl, n=1, ) was studied by NMR methods and IR spectroscopy. Two approaches were used: (1) the substitution reaction of triphenylphosphine in RhH(CO)(PPh3)3 by an amphiphilic phosphine and (2) a reaction between the precursor Rh(acac)(CO)2, syngas and the amphiphilic ligand in hydroformylation reaction conditions. Both approaches show the formation of P-coordinated hydridorhodium(I) complexes

The catalytic selective hydrogenation of an α,β-unsaturated aldehyde (prenal) with ruthenium complexes prepared in situ from RuCl3 and ligands 1−6 has been carried out in a 2-propanol/water mixture. Conversions to prenol to the order of 90% or higher are observed with selectivity of 90−96% after 20 min at P = 30 bar and T = 50 °C. The most active systems

  A series of trans-PdCl2L2 complexes were prepared and characterized with the following hemilabile amphiphilic phosphines: R-(C6H4)-(OCH2CH2)(n)-PPh2 1 (R = tert-octyl, n = 1), 2 (R = tert-octyl, (n) over bar = 5), 3 (R = tert-octyl, (n) over bar = 13), 4 (R = n-nonyl, (n) over bar = 1.4), 5 (R = n-nonyl, (n) over bar = 5), 6 (R = n-nonyl, (n) over bar = 11)}, CH3(OCH2CH2)(3)PPh2 (7), CH3(OCH2CH2)(3)PPhR (8, R = isopentyl) and HOCH2CH2(OCH2CH2)(2)PPhR (9, R=n-octyl). The molecular structure of trans-PdCl2(1)(2) was determined by X-ray crystallography. The reaction between the trans-PdCl2L2 complexes and Ag+. was studied by P-31-NMR spectroscopy. The formation of chelated P boolean ANDO species in tetrahydrofuran solution was observed in complexes with ligands 2, 3, 5, 6, 7, 8 and 9. However, with ligand 1 the formation of chelated species was only observed in the less coordinating solvent dichloromethane. This different behavior can be attributed to the electronic and steric effects of the aryl group bonded to the oxygen atom. Ligand 4 is a mixture of a molecule similar to 1 and molecules with more than one oxygen atom and thus displays both characteristics. (C) 2001 Elsevier Science B.V. All rights reserved.
