  • Synthesis and chemistry of trans-[RhX(CO)L2](X = anionic ligand, L = tertiary phosphine)
    作者:Yuji Ohgomori、Shin-ichi Yoshida、Yoshihisa Watanabe
    DOI:10.1039/dt9870002969
    日期:——
    trans-[RhX(CO) L2] complexes (X = anionic ligand, L = tertiary phosphine) from [Rh4(CO)12], phosphine (L), and acid (HX) is described. A plausible formation pathway is proposed. The electron density on the phosphorus atom in trans-[RhX(CO)L2] decreases and the length of the Rh–P bond increases with an increase in the electronegativity of the anionic ligand, X, in a cis position to the phosphine ligand. The rhodium
    由[Rh 4(CO)12 ],膦(L)和酸(HX)制备多种反式-[RhX(CO)L 2 ]复合物(X =阴离子配体,L =叔膦)描述。提出了一条合理的形成途径。反式-[RhX(CO)L 2 ]中原子上的电子密度降低,并且Rh–P键的长度随着阴离子配体X(与膦配体的顺式)电负性的增加而增加。还原配合物(X =芳基羧酸盐),得到酸盐阴离子,例如[Rh(CO)3 L] –和[Rh(CO)4 ] –在CO–H 2下的六甲基酰胺溶液中。还原速率随着芳基羧酸配体的吸电子作用的降低而增加。
  • A model study of the mechanism of the homogeneous catalytic hydroformylation of formaldehyde
    作者:Albert S.C. Chan
    DOI:10.1016/s0020-1693(00)82815-7
    日期:1993.8
    Abstract The anionic mechanism for the Rh-catalyzed hydroformylation of formaldehyde was supported by the synthesis of a key model rhodium acyl intermediate which, upon hydrogenolysis, gave the model product and regenerated the catalyst.

  • High-Pressure Infrared Studies of Rhodium Complexes Containing Thiolate Bridge Ligands under Hydroformylation Conditions
    作者:Montserrat Diéguez、Carmen Claver、Anna M. Masdeu-Bultó、Aurora Ruiz、Piet W. N. M. van Leeuwen、Gerard C. Schoemaker
    DOI:10.1021/om990003o
    日期:1999.5.1
    In situ high-pressure IR spectroscopy studies of the rhodium catalyst systems [Rh2μ-S(CH2)3N(Me2)}2(COD)2]/PR3 (R = Ph, OPh), [Rh2μ-S(CH2)2S}(COD)2]/PPh3, [Rh2μ-S(CH2)4S}(COD)2]2/PPh3, [Rh2μ-XANTOSS}(COD)2]2/PPh3, and [Rh(acac)(CO)2]/PR3 (R = Ph, OPh) revealed the presence of mononuclear rhodium hydride species under hydroformylation conditions (80 °C, 5−30 bar). The activities and selectivities
    催化剂体系[Rh 2 μ-S(CH 2)3 N(Me 2)} 2(COD)2 ] / PR 3(R = Ph,OPh),[Rh 2 μ-S(CH 2)2 S}(COD)2 ] / PPh 3,[Rh 2 μ-S(CH 2)4 S}(COD)2 ] 2 / PPh 3,[Rh 2 μ -XANTOSS}(COD)2 ] 2 / PPh 3和[Rh(acac)(CO)2 ] / PR3(R = Ph,OPh)显示在加氢甲酰化条件下(80°C,5-30 bar)存在单核氢化。使用这些体系作为催化剂前体,在1-己烯加氢甲酰化过程中获得的活性和选择性可以由所观察到的单核物种充分解释。使用双核[Rh 2 μ-S(CH 2)3 N(Me 2)} 2(COD)2 ] / PR 3系统进行的代甲酰化实验不支持双核机制。
  • Rhodium hydride (HRh(CO)(PPh3)3) and rhodium carbonyl (Rh4(CO)8L4) complexes obtained by reaction of Rh(acac)(CO)(L) type complexes with methanol and formaldehyde
    作者:A.M. Trzeciak、J.J. Ziółkowski
    DOI:10.1016/0022-328x(92)83254-f
    日期:1992.5
    Rhodium(I) complexes of Rh(acac)(CO)(L) type (where L = P(OMe)3, P(OEt)3, P(OPh)3, P(O-o-MeC6H4)3, PPh3, P(p-MeC6H4)3, PMePh2, AsPh3) react with alcohols and formaldehyde. In absence of free ligand (L) only carbonyl complexes of formula Rh4(CO)8(L)4 (or Rh4(CO)12-x(L)x) are formed. Reaction of Rh(acac)(CO)(PPh3) with methanol or formaldehyde in the presence of free PPh3 leads to the formation of HRh(CO)(PPh3)3
    Rh(acac)(CO)(L)类型的(I)配合物(其中L = P(OMe)3,P(OEt)3,P(OPh)3,P(O- o- MeC 6 H 4)3,PPh 3,P(p -MeC 6 H 4)3,PMePh 2,AsPh 3)与醇和甲醛反应。在不存在游离配体(L)的情况下,仅形成式Rh 4(CO)8(L)4(或Rh 4(CO)12- x(L)x)的羰基配合物。Rh(acac)(CO)(PPh)的反应3)在游离PPh 3存在下用甲醇甲醛导致仅形成HRh(CO)(PPh 3)3。
