    Steric and electronic factors in the promoting activity of diphosphine ligands in cyclohexene hydrocarbomethoxylation catalyzed by palladium acetate
    摘要:
    Cyclohexene hydrocarbomethoxylation catalyzed by Pd(OAc)(2)-p-toluenesulfonic acid-diphosphine systems has been investigated for a wide range of diphosphine structures and concentrations. The factors controlling the activity of the palladium-containing catalysts include the hydrocarbon moiety of the ligand and the mutual arrangement of the phosphine groups. A comparison between the promoting effects of monophosphine and diphosphine ligands has demonstrated that bridged trans-diphosphines are more efficient in kinetic and concentration terms (TOF and P/Pd ratio, respectively). In particular, the promoting activity of diphosphines is one order of magnitude higher than that of triphenylphosphine, and this effect is attained at 8-65 times lower P/Pd ratios. It is discussed how the catalytic properties of the systems depend on the chelate effect and on the geometric compatibility between the diphosphine structure and the arrangement of vacant s and d orbitals of the palladium center.

    provides polyfunctional phosphines in good yields. Especially attractive is the hydroboration/boron-zinc exchange sequence which allows the conversion of functionalized olefins into polyfunctional phosphines in a one-pot procedure. Several new chiral phosphines have been prepared starting from readily available chiral olefins (terpenes) and their efficiency in asymmetric hydrogenation reactions has been

    Optically active expanded chelate phosphines were synthesised by reaction of bromotolyl, bromoxylyl and bromodiphenylmethane derivatives with 1,ω-bis(dichlorophosphino)alkanes. The bromotolyl, bromoxylyl and bromodiphenylmethane ethers were obtained from the corresponding bromo(bromomethyl)arenes and the optically active alcohol (−)-borneol.

    Reaction of RSO2N(H)CH2CH2N(H)SO2R [R = Bu (1), 4-nitrobenzene (7), 1-naphthalene (9a), 2-naphthalene (9b)] with PhPCl2 or EtPCl2 gives monodentate phosphorus compounds 2 and 3 (R = Bu, PhP and EtP), and 8 (R = 4-nitrobenzene, PhP), and with Ph2PCl gives the corresponding bidentate phosphine ligands Ph2PN(SO2R)CH2CH2N(SO2R)PPh2 [R = Bu (10), 4-nitrobenzene (11), 1- and 2-naphthalene (12a,b)]; similar reactions of N,N′-(1-butanesulfonyl)-2,2′-diaminobiphenyl (4) give monodentate 5 (PhP) and 6 (EtP) and N,N′-bis(diphenylphosphino)-N,N′-(1-butanesulfonyl)-2,2′-diaminobiphenyl (16). A monodentate analogue of 10 was also prepared, Ph2PN(Et)SO2Bu (14). Diphosphorus compounds with two butanesulfonylamino groups on phosphorus were also prepared from 1 and Cl2P(CH2)nPCl2 (n = 2, 4) to give 19 and 20. Details of the 13C NMR false AA′X systems are reported for 19 and 20. Rhodium-catalyzed hydroformylation reactions were run at 60 and 80 °C, at CO/H2 pressures from 4–11 atm, and in THF, toluene, CH2Cl2, and dioxane. Results show that the highest ratios of linear (n) to branched (iso) aldehydes were obtained with arenesulfonamides (n∶iso > 10) while the bidentate alkanesulfonamide 10 gave a lower n∶iso ratio of 7.2 but the highest rate [k1 = 1.98 h−1, turnover frequency = 1130 mol aldehyde (mol Rh)−1 h−1] in THF at 80 °C. Both the rate and n∶iso ratio for 10 were found to increase with decreasing CO/H2 pressure in THF and in toluene, although the rate change was small for toluene. Both the rate and n∶iso ratio for 10 also increased in CH2Cl2, but this was found not to be due to lower CO/H2 concentrations in solution, on the basis of solubility measurements in THF and CH2Cl2.
    RSO2N(H)CH2CH2N(H)SO2R [R = Bu (1)、4-硝基苯 (7)、1-萘 (9a)、2-萘 (9b)]与 PhPCl2 或 EtPCl2 反应生成单齿磷化合物 2 和 3(R = Bu、PhP 和 EtP)、和 8(R = 4-硝基苯、PhP),而与 Ph2PCl 反应则可得到相应的双齿膦配体 Ph2PN(SO2R)CH2CH2N(SO2R)PPh2[R = Bu (10)、4-硝基苯 (11)、1-和 2-萘 (12a,b)];N,N′-(1-丁烷磺酰基)-2,2′-二氨基联苯(4)的类似反应可得到单齿 5(PhP)和 6(EtP)以及 N,N′-双(二苯基膦)-N,N′-(1-丁烷磺酰基)-2,2′-二氨基联苯(16)。此外,还制备出了 10 的单齿类似物 Ph2PN(Et)SO2Bu (14)。由 1 和 Cl2P(CH2)nPCl2(n = 2,4)还制备出了磷上带有两个丁烷磺酰胺基团的二磷化合物,得到了 19 和 20。报告了 19 和 20 的 13C NMR 假 AA′X 系统的详细信息。铑催化的加氢甲酰化反应在 60 和 80 °C、4-11 atm 的 CO/H2 压力以及 THF、甲苯、CH2Cl2 和二噁烷中进行。结果表明,壬磺酰胺(n∶iso > 10)得到的线性(n)醛与支链(iso)醛的比率最高,而双叉烷磺酰胺 10 在 80 ℃ 的 THF 中得到的 n∶iso 比率较低,为 7.2,但速率最高 [k1 = 1.98 h-1,翻转频率 = 1130 摩尔醛(摩尔 Rh)-1 h-1]。在 THF 和甲苯中,10 的速率和 n∶iso 比率都随着 CO/H2 压力的降低而增加,尽管甲苯中的速率变化较小。在 CH2Cl2 中,10 的速率和 n∶iso 比率也有所增加,但根据在 THF 和 CH2Cl2 中的溶解度测量,发现这并不是由于溶液中 CO/H2 浓度降低所致。

    The reaction of tetrachlorodiphosphines [Cl2P(CH2)nPCl2; n = 2-4] with fluorous aromatic precursors 4-bromo(perfluorohexyl)benzene and 4-(perfluorohexyl)phenol gave a series of fluorous-tagged diphosphines [(p-C6F13C6H4)2P(CH2)nP(C6H4C6F13-p)2; n = 2-4] and a new diphosphonite [(p-C6F13C6H4O)2P(CH2)3P(OC6H4C6F13-p)2]. The improved synthesis of 1,3-bis(dichlorophosphino)propane (dcpp), involved the facile chlorination of the corresponding primary phosphine with triphosgene. Fluorinated diimines RN=C(CH3)C(CH3)=NR, where R = p-C6H4C6F13 or p-C6H4C8F17 have also been prepared, and were found to be air-stable alternatives to the highly air-sensitive phosphorus-containing ligands. All compounds were characterised by a variety of techniques including NMR, IR, MS and microanalysis. The successful reduction of the phosphine-oxides [(p-C6F13C6H4)2P(O)(CH2)nP(O)(C6H4C6F13-p)2; n = 2,3] with phenylsilane is also presented.
