    Synthesis, Structure, and Reactivity of Mononuclear Re(I) Oximato Complexes
    摘要:
    Complexes [Re(ONCMe2)(CO)(3)(bipy)] (1) and [Re(ONCMe2)(CO)(3)(phen)] (2), synthesized by reaction of the respective triflato precursors [Re(OTf)(CO)(3)(N-N)] (N-N = bipy, phen) with KONCMe2, feature O-bonded monodentate oximato ligands. Compound [Re(CO)(3)(phen)(HONCMe2)]BAr'(4) (3), with a monodentate N-bonded oxime ligand, was prepared by reaction of [Re(OTf)(CO)(3)(phen)], HONCMe2, and NaBAr'(4). Deprotonation of 3 afforded 2. The oximato complexes reacted with p-tolylisocyanate, p-tolylisothiocyanate, maleic anhydride, and tetracyanoethylene, affording the products of the insertion of the electrophile into the Re-O bond, compounds 4-7. One representative of each type of compound was fully characterized, including single-crystal X-ray diffraction. The reactions of 1 and 2 with dimethylacetylenedicarboxylate were found to involve first an insertion as the ones mentioned above but followed by incorporation of water, loss of acetone, and formation of the charge-separated neutral amido complexes 9 and 10. The structure of 9 and 10 was determined by X-ray diffraction, and key features of their electronic distribution were studied using a topological analysis of the electron density as obtained from the Fourier map.

    fac-[Re(Cl)(CO)3(stpy)2] and fac-[Re(stpy)(CO)3(bpy)]+ (stpy = t-4-styrylpyridine, bpy = 2,2'-bipyridine) show that their lowest absorption bands are dominated by stpy-localized intraligand (IL) pi pi* transitions. For the latter complex a Re --> bpy transition contributes to the low-energy part of the absorption band. Optical population of the 1IL excited state of fac-[Re(Cl)(CO)3(stpy)2] is followed by

It is concluded that coordination of papy to the Re center accelerates the ISC, switching the photochemistry from singlet to triplet excited states.

    Two pyridine substituted beta-cyclodextrins have been synthesized and coordinated to the photoactive metal centres, [Ru(II)(bpy)2] and [Re(I)(CO)3bpy], where bpy is 2,2'-bipyridyl. The photophysical and electrochemical properties of these model complexes have been examined and compared with dinuclear complexes formed when C60 was included between two cyclodextrin cavities of the metallocyclodextrin
    已合成了两个吡啶取代的β-环糊精,并与光敏属中心[Ru(II)(bpy)2]和[Re(I)(CO)3bpy]配位,其中bpy是2,2'-联吡啶。这些模型配合物的光物理和电化学性质已经过检查,并与在环糊精单元的两个环糊精腔之间包含C60时形成的双核配合物进行了比较。包含C60时,观察到发光体的发射显着淬灭。浓度和激光功率依赖性证实该淬灭是分子内的。根据光谱和电化学证据,根据光敏剂和C60中心之间的光诱导电子转移来解释淬灭过程。速率常数为1.3 +/- 0.1 x 10(8)和7.0 +/- 0。分别确定了基于Ru和Re的络合物的4 x 10(7)s(-1)。显着地,这些大的速率常数表明至少对于激发态过程,整个环糊精存在大量电子通信。
