    Photorelease of Primary Aliphatic and Aromatic Amines by Visible-Light-Induced Electron Transfer
    摘要:
    Visible-light-absorbing tris(bipyridyl)ruthenium(II) has been used to mediate electron transfer to N-methylpicolinium carbamates that undergo C-O bond fragmentation followed by spontaneous carbon dioxide release to give free amines. Release of several aliphatic and aromatic primary amines has been demonstrated under mild conditions using visible light.

    [structure: see text]. The synthesis and nonlinear optical characterization of two novel heteroaromatic-based chromophores is described. The new dyes present an A-pi-D-pi-A general framework, where A is a pi-deficient heteroaromatic ring (pyridine, quinoline, benzothiazole) and D a pi-excessive pyrrolyl moiety. Both systems exhibit large two-photon absorption (TPA) values in the femtoseconds regime

    N-heterocyclic carbenes having only one N atom (NHC1N-R6 carbenes) can be easily prepared by simple deprotonation of readily available N-methylpyridinium-type cations with K[N(SiMe3)2]. They have been trapped in solution with [Ru3(CO)12] to give novel triruthenium clusters that contain orthometalated NHC1N-R6 carbene ligands in a face-capping coordination mode.

    Near-infrared-emitting hemicyanine dyes are widely used in activatable fluorescent probes for various biological analytes; however, they are chemically unstable and show photoinstability, as shown here with naphthalene-based hemicyanines containing a typical hemicyanine moiety, 2-indolium. These issues can be resolved with a 4-pyridinium derivative, which also has good two-photon imaging capability

    intermediates in many reactions, therefore, new methods to achieve them are anticipated. In this study, a formal [3+2] method, through the reactions of an osmapentalyne with benzyl carbanions, was developed. The reactions underwent a nucleophilic attack of carbanions to the Os≡C bond, followed by C—H activation to form the five-membered osmacyclopentadiene ring. Most of the reactions were carried out at
    金属环戊二烯是重要的金属环化合物,在许多反应中被视为中间体,因此,期望有新的方法来实现它们。在这项研究中,开发了一种正式的[3+2]方法,通过osmapentalyne与苄基碳负离子的反应。该反应经历了碳负离子对Os≡C键的亲核攻击,然后是CH活化形成五元环戊二烯环。大多数反应在室温下进行,苄基碳负离子芳环上的取代基多样,所得产物含有Os-H键,代表了一种新型的10C-碳龙配合物。该工作为构建金属环戊二烯提供了一条新的便捷途径,有望进一步推动该类物质的发展。
