    苯与VIB族五羰基金属和四羰基金属气相反应的时间分辨IR研究
    摘要:
    The gas-phase reactions of benzene and deuterated benzene (benzene-d(6)) with group VIB metal pentacarbonyls M(CO)(5) (M = Cr and W) and tetracarbonyl W(CO)(4) were probed with time-resolved infrared spectroscopy. Benzene reacts with M(CO)(5) forming presumably (eta(2)-benzene)M(CO)(5) in which benzene coordinates to the metal via an isolated double bond. The rate constants for reactions of C6H6 and C6D6 with Cr(CO)5 were found to be (3.0 +/- 0.7) and (3.3 +/- 0.2) x 10(13) cm(3) mol(-1) s(-1), respectively. The corresponding values with W(CO)(5) are (2.8 +/- 0.4) and (3.5 +/- 0.6) x 10(13) cm(3) mol(-1) s(-1). From the temperature dependence of rate of dissociative loss of benzene from (eta(2)-benzene)Cr(CO)(5), a bond dissociation energy of 9.2 +/- 0.8 kcal mol(-1) was determined for (eta(2)-benzene)Cr(CO)(5). The lower limit for bond dissociation energy for loss of the benzene ligand from (eta(2)-benzene)W(CO)(5) was estimated to be 11.7 kcal mol(-1). Benzene reacts with W(CO)(4) producing a species, presumably (eta(2)-benzene)W(CO)(4), which is stable in the millisecond time scale. The rate constants for reactions of C6H6 and C6D6 With W(CO)(4) were determined to be (3.5 +/- 0.2) and (4.1 +/- 0.4) x 10(13) cm(3) mol(-1) s(-1) respectively. Secondary addition of CO to (eta(2)-benzene)W(CO)(4) forms (eta(2)-benzene)W(CO)(5), and the rate constants are (9.4 +/- 0.9) and (8.7 +/- 1.0) X 10(11) cm(3) mol(-1) s(-1), respectively, for additions of CO to (eta(2)-C6H6)W(CO)(4) and (eta(2)-C6D6)W(CO)(4).

  • Conical intersections, pseudorotation and coherent oscillations in ultrafast photodissociation of group-6 metal hexacarbonyls

    repulsive ligand-field surface and dissociate. The primary product is M(CO)5 in its S1 state which can again relax in an ultrashort time through a JT induced conical intersection to S0; the JT active coordinate (relaxation pathway) corresponds to pseudorotation. The total time to reach S0 takes 110, 165 and 195 fs for the three carbonyls (calculated from the measured first four time constants). After arrival
    通过时间分辨的非共振(800 nm)多光子电离,我们发现了五个连续的过程,并且在气相中以267 nm激发M(CO)6,M = Cr,Mo和W之后,出现了明显的相干振荡。我们建议前两个步骤对应于沿Jahn-Teller(JT)活性坐标的弛豫和通过JT诱导的圆锥形交点在金属到配体的电荷转移状态之间进行内部转换,而在第三步中,分子转换为排斥性配体场表面并解离。主要产物是处于S 1状态的M(CO)5,它可以在超短时间内通过JT诱导的与S 0的圆锥形交点而弛豫。; JT活动坐标(松弛路径)对应于伪旋转。对于三个羰基(从测得的前四个时间常数计算),达到S 0的总时间分别为110、165和195 fs。在到达S 0之后,M(CO)5沿着伪旋转坐标相干振荡。在S 0中,M(CO)5由于其振动过量能量而在大约1 ps的时间内消除了第二个CO,该步骤通过冷却在溶液中得到抑制。所有过程都在状态的单重态中进行。

    Photolysis of the Group 6 metal hexacarbonyls in hydrocarbon glasses at 80 K gives rise to species M(CO)n(n= 3–5), presumably weakly solvated, by successive CO loss. Primary and subsequent processes both show photo-reversal. Slow warming leads to recombination, hexacarbonyl precipitation, poorly defined, possibly polymeric species, and formation of species [M(CO)5(OH2)]. Visible-u.v. and i.r. spectra

    NMR and photochemistry are reported for the complexes M(CO)4bpym (M = Cr or W) and [W(CO)4]2bpym. The electronic absorption spectra indicate, for these complexes, that the lowest lying metal-to-ligand (L) charge transfer (MLCT) excited state is lower in energy than the ligand field (LF) excited states. The 13C NMR spectra showed that the chemical shifts of C(5) and C(6) for the M-bpym complexes move downfield
    摘要报道了配合物M(CO)4bpym(M = Cr或W)和[W(CO)4] 2bpym的合成,电子吸收光谱,13C NMR和光化学。对于这些配合物,电子吸收光谱表明,最低位的金属-配体(L)电荷转移(MLCT)激发态的能量低于配体场(LF)激发态。13 C NMR谱图显示,M-bpym配合物的C(5)和C(6)的化学位移相对于游离配体bpym而言向低场移动,而C(4)在络合时向高场移动。在辐射下获得了小量的,随波长而变的CO损失的量子产率。Cr-bpym络合物的这些量子产率比W络合物大一个数量级(Cr-bpym的Φ= 2.4 x 10-2 Quanta / min,W-bpym的为2.5 x 10-3 Quanta / min和1 。

    Abstract The infrared and UV-visible spectra of W(CO) 5 PCl 3 in a Ar matrix at 10 K presented. The UV-visible photolysis of W(CO) 5 PCl 3 with different wavelengths (λ = 229, 254, 280, 313 and 366 nm) resulted in release of phsphorous trichloride. This remarkable photochemical behaviour of W(CO) 5 PCl 3 , different from W(CO) 5 (amine) is discussed in terms of a m.o. scheme. The complete infrared
