    以前已报道过Rh(PMe 3)2 ClL'(L'= CO或三取代的膦)和[Rh(PMe 3)2 Cl] 2形式的配合物可使用烯烃氢受体在二氢气氛。据报道,在没有H 2的情况下,即使在更高的温度下,这种配合物也能实现转移-脱氢,但速率和总催化转化率要低得多。发现与氯化物以外的卤化物(Br,I)或假卤化物(OCN,N 3)的类似物表现出大致相似的行为:在H 2下具有高催化活性和在没有H 2的情况下可测量但活性低得多。在不存在氢受体的情况下,在环辛烷中热解(在氩气下)配合物[RhL 2 Cl] n(n = 1,2; L是比PMe 3更大的膦),生成环辛烯。然而,转移-脱氢受到配体分解的困扰。在氢气氛下,含有比PMe 3体积大得多的配体的络合物不影响脱氢作用。具有三齿配体的络合物,(η 3 -PXP)RHL'(PXP =(ME 2 PCH 2我2 Si)的2 N,我2 PCH 2(2,6-C 6 H

    The syntheses of two pentadentate tetrapodal phosphine (pentaPodP) ligands, P2PhPP2Ph and P2MePP2Ph, are reported, which derive from the fusion of a tripod and a trident ligand. Reaction of the ligand P2PhPP2Ph with [MoCl3(THF)3] followed by an amalgam reduction under N2 does not lead to well-defined products. The same reactions performed with the ligand P2MePP2Ph afford the mononuclear molybdenum

  • Bond Activation in Iron(II) and Nickel(II) Complexes of Polypodal Phosphanes

    A pyridine-derived tetraphosphane ligand (donor set: NP4) has been found to undergo remarkably specific C-P bond cleavage reactions, thereby producing a ligand with an NP3 donor set. The reaction may be reversed under suitable conditions, with regeneration of the original NP4 ligand. In order to investigate the mechanism of this reaction, the NP3 donor ligand C5H3N[CMe(CH2PMe2)2][CMe2(CH2PMe2)] (11) was prepared, and its iron(II) complex 4 generated from Fe(BF4)2 ・6H2O, with methyl diethylphosphinite (7) as an additional monodentate ligand. Ligand 11 has, in addition to the NP3 donor set, one methyl group in close contact with the iron center, reminiscent of an agostic M・ ・ ・H-C interaction. Depending on the stoichiometric amount of iron(II) salt, a side product 15 is formed, which has a diethylphosphane ligand instead of the phosphinite 7 coordinated to iron(II). While attempts to deprotonate the metal-coordinated methyl group in 4 were unsuccessful, the reaction was shown to occur in an alternative complex (18), which is similar to 4 but has a trimethylphosphane ligand instead of the phosphinite 7. The reaction of complex 15 with CO gave two different products, which were both characterized by single-crystal X-ray diffraction. One (19) is the dicarbonyl iron(II) complex of the triphosphane ligand 11, the other (3) is the carbonyl iron(II) complex of the tetraphosphane C5H3N[CMe(CH2PMe2)2]2 (1). This suggests an intermolecular mechanism for the C-P bond formation in question.

    一种由吡啶衍生的四膦配体(给体组:NP4)已被发现能够经历非常特异的C-P键裂解反应,从而产生一个具有NP3给体组的配体。在适当条件下,该反应可以被逆转,原始的NP4配体可以再生。为了研究这种反应的机制,制备了NP3给体配体C5H3N[CMe(CH2PMe2)2][CMe2(CH2PMe2)](11),并且通过Fe(BF4)2・6H2O生成了其铁(II)配合物4,其中甲基二乙基膦酸酯(7)作为额外的单齿配体。配体11除了具有NP3给体组外,还有一个与铁中心紧密接触的甲基基团,类似于一个Agostic M・ ・ ・H-C相互作用。根据铁(II)盐的化学计量比,会形成一个副产物15,该副产物具有一个二乙基膦配体,而不是与铁(II)配位的膦酸酯7。尽管试图去脱质子化金属配位的甲基基团未成功,但该反应被证明发生在另一个类似于4的替代配合物(18)中,该替代配合物具有三甲基膦配体,而不是膦酸酯7。配合物15与CO的反应产生了两种不同的产物,两者均通过单晶X射线衍射进行了表征。其中一种(19)是三膦配体11的二羰基铁(II)配合物,另一种(3)是四膦C5H3N[CMe(CH2PMe2)2]2(1)的羰基铁(II)配合物。这表明所涉及的C-P键形成可能是一种分子间机制。
