    摘要:
    苄基阳离子是高活性化合物,是各种化学和生物化学过程的中间体。在这项工作中,金属配位用于稳定苄基阳离子的不同配位模式,包括亚甲基芳烃(MA),π-苄基和σ-苄基配合物。研究了两个双齿配体骨架,二苯基膦基乙烷(dppe)和二叔丁基膦基丙烷(dtpp)。η 2 -Coordination与Pd(II)允许在环境条件下的未观测否则亚甲基arenium物质的反应性的表征和研究。的三种形式的协调苄分子,η的相对稳定性和电子结构2 -MA,η 1 -σ-苄,η 3-π-苄基,通过实验和计算进行了研究。在不存在抗衡阴离子的情况下,MA和π-苄基结构是优选的,而dtpp庞大的配体有助于亚甲基芳烃形式的稳定。抗衡阴离子对相对稳定性有重大影响。由于对MA环上的正电荷进行补偿,三氟甲磺酸根阴离子在配位至金属中心或亚甲基芳烃形式时稳定了σ-苄基形式。非配位BArF抗衡阴离子的使用促进了向π-苄基形式的转化。

    名称:
    Palladium Complexes with Bulky Diphosphine Ligands as Highly Selective Catalysts for the Synthesis of (Bio-) Adipic Acid from Pentenoic Acid Mixtures.
    摘要:
    A series of sterically bulky diphosphines have been prepared, including P-2 = trans-1,2-bis[(di-tert-butylphosphino)methyllcydohexane (4), (2-methylenepropane1,3-diy1)bis(di-tert-butylphosphine) (5), bis[(di-tertbutylphosphino)methyl]dimethylsilane (6), and cis- and trans11,12-bis [ (di-tert-butylphosphino)methy1]-9,10-dihydro-9,10-ethanoanthracene (10 and 11). The corresponding palladium complexes of these ligands, P2Pd(CF3CO2)(2), have been synthesized and characterized. The solid-state structures of [Pd(4)(CF3CO2)(2)], [Pd(S)(CF3CO2)(2)], [Pd(6)(CF3CO2)(2)], and [Pd(11)(CF3CO2)(2)] were obtained by single-crystal X-ray diffraction and confirm the bidentate binding mode of the ligand and a square-planar coordination geometry with a minor distortion from the ideal. The diphosphines in combination -with Pd(OAc)(2) have been applied in the hydroxycarbonylation of a mixture of pentenoic acid isomers to produce adipic acid with high selectivity (in several cases >95%). The (regio)selectivity of the hydroxycarbonylation reaction is highly dependent on the P-2 diphosphine ligand structure, particularly the steric bulk of the substituents on the diphosphine donor and the P-Pd-P bite angle in the complexes, with respectively tertiary alkyl phosphine substituents (tert-butyl, adamantyl) and a C4 backbone P-Pd-P bite angle >100 degrees being the common features of highly adipic acid selective systems. It is suggested that the regioselectivity of hydroxycarbonylation becomes largely driven by the chelation of the carboxylic acid functionality of pentenoic acid substrates, when smaller size P substituents and/or when P-2 ligands with smaller bite angles (<100 degrees) are applied.

  • A Comprehensive Mechanistic Picture of the Isomerizing Alkoxycarbonylation of Plant Oils

    olefin substrates, but virtually no effect of the double bond position within the substrate. Compared to higher olefins, ethylene carbonylation under identical conditions is much faster, likely due not just to the occurrence of reactive linear acyls exclusively but also to an intrinsically favorable insertion reactivity of the olefin. The alcoholysis reaction is slowed down for higher alcohols, evidenced
    对异构化烷氧基羰基化的整个催化循环的理论研究表明,二膦配位的 Pd 中心周围的空间拥挤是选择性和生产率的决定性因素。异构化的能量分布对于可变空间体积的二膦是平坦的,但是对于空间要求高的二膦更倾向于形成直链 Pd-烷基物种。对于所有研究的 Pd-烷基物质,CO 插入是可行和可逆的,并且受二膦影响很小。与最高能量屏障相关的总体限速步骤是 Pd-酰基物质的甲醇分解。考虑到线性 Pd-酰基物质的甲醇分解,其能量势垒在所有研究的 Pd-酰基物质中最低,计算出的势垒对于更拥挤的二膦更低。计算表明,对于体积更大的二膦,线性与支化 Pd-酰基的甲醇分解能量差异更为明显,这是由于在过渡态中涉及不同数量的甲醇分子。在压力反应器条件下的实验研究表明,较短链烯烃底物的转化速度更快,但底物内的双键位置几乎没有影响。与高级烯烃相比,相同条件下的乙烯羰基化速度要快得多,这可能不仅是由于反应性线性酰基的出现,而且还因为烯
