  • The hydrogen atom transfer reactivity of sulfinic acids
    作者:Markus Griesser、Jean-Philippe R. Chauvin、Derek A. Pratt

    thiols (∼107 M−1 s−1) and sulfenic acids (∼109 M−1 s−1). Importantly, since sulfinic and sulfenic acids are very strong H-bond donors (αH2 ∼ 0.63 and 0.55, respectively), their reactivity is greatly attenuated in H-bond accepting solvents, whereas the reactivity of thiols is largely solvent-independent. Efforts to measure rate constants for the reactions of sulfinic acids with alkylperoxyl radicals were
    亚磺酸(RSO 2 H)因其容易自氧化而成为困难的试剂而闻名。然而,近来它们已在各种有用的自由基链反应中用作关键试剂。为了解决这一矛盾,并使使用亚磺酸的自由基反应得以进一步发展,我们首次表征了其H原子转移反应的热力学和动力学。通过自由基平衡确定亚磺酸的OH键离解焓(BDE)为〜78 kcal mol -1;大致中途的RS-H BDE在硫醇(~87千卡mol之间-1)和RSO-H BDE在次磺酸(约70千卡摩尔-1)。无论如何,RSH,RSOH和RSO 2H与烷基具有相对​​相似的固有H原子转移反应性(〜10 6 M -1 s -1)。与直觉相反,具有更多反应性烷氧基的速率常数趋势遵循反应能量:RSO 2 H约为10 8 M -1 s -1,硫醇(约10 7 M -1 s -1)和亚硫酸之间(〜10 9 M -1 s -1)。重要的是,由于亚和次磺酸都非常强的氢键供体(α ħ 2分别为约0.63和0
  • Solid-State Photodecarbonylation of Diphenylcyclopropenone:  A Quantum Chain Process Made Possible by Ultrafast Energy Transfer
    作者:Gregory Kuzmanich、Arunkumar Natarajan、Khin K. Chin、Marcel Veerman、Christopher J. Mortko、Miguel A. Garcia-Garibay

    日期:2008.1.30
    It has been reported that electronic excitation of diphenylcyclopropenone (DPCP) into the second excited state (S2) results in an adiabatic ring-opening process within 200 fs to give an excited product with a lifetime of ca. 8 ps in S2. Knowing that energy transfer in crystals may occur within 1−2 ps, we recognized that the conditions could be right for a quantum chain process with the excited-state
    据报道,二苯基环丙烯酮 (DPCP) 进入第二激发态 (S2) 的电子激发会导致在 200 fs 内发生绝热开环过程,从而得到寿命为约 10 的激发产物。S2 为 8 ps。知道晶体中的能量转移可能在 1-2 ps 内发生,我们认识到条件可能适合量子链过程,激发态产物使相邻的基态反应物敏感以建立多米诺骨牌效应。与此一致,我们发现激发或宏观晶体会导致非常有效的反应,通过释放大量机械能的过程得到二苯乙炔作为多晶粉末。
  • Alkali metal ion controlled product selectivity during photorearrangements of 1-naphthyl phenyl acylates and dibenzyl ketones within zeolites
    作者:M Warrier、Lakshmi S Kaanumalle、V Ramamurthy
    DOI:10.1139/v03-041
    日期:2003.6.1
    acylates and dibenzyl ketones included in zeolites have been compared. 1-Naphthyl phenyl acylates while in solution produce eight photoproducts; within NaY it gives a single product. The selectivity is attributed to the restriction brought on the mobility of the primary radical pair by the alkali metal ions present in zeolites. Photochemistry of dibenzyl ketones within NaY reveals that the intersystem crossing
    比较了沸石中包含的 1-萘基苯基酰化物和二苄基酮的光化学行为。1-萘基苯基酰化物在溶液中产生八种光产物;在 NaY 中,它提供了一个单一的产品。选择性归因于沸石中存在的碱金属离子对初级自由基对的迁移率的限制。NaY 内二苄基酮的光化学表明笼自由基对中的系统间交叉可能受重碱金属离子的影响。在 B3LYP 水平计算的 Li+ 离子与客体 1-萘基苯乙酸酯和二苄基酮之间的配合物结构有助于理解沸石内观察到的产物选择性的起源。关键词:photo-Fries 反应,沸石,阳离子? π 相互作用、自旋轨道耦合、重原子效应。
  • Heavy cation effect on intersystem crossing between triplet and singlet phenylacyl and benzyl geminate radical pairs within zeolites
    作者:Manoj Warrier、Nicholas J Turro、V Ramamurthy
    DOI:10.1016/s0040-4039(00)01199-0
    日期:2000.9
    observed between dibenzyl ketones and naphthyl esters in zeolites is due to the difference in spin of the radical pairs formed from these precursors. Heavy cations present in zeolites can enhance intersystem crossing between triplet and singlet geminate radical pairs.
    在沸石中二苄基酮和萘基酯之间观察到的产物选择性的差异是由于由这些前体形成的自由基对的自旋差异。沸石中存在的重阳离子可增强三重态和单重态自由基对之间的系统间穿越。
  • Enhanced Cage Effects in Supercritical Fluid Solvents. The Behavior of Diffusive and Geminate Caged-Pairs in Supercritical Carbon Dioxide
    作者:James M. Tanko、Ryszard Pacut
    DOI:10.1021/ja002800f
    日期:2001.6.1
    The behavior of geminate and diffusive radical caged-pairs arising from the photolysis of dicumyl ketone in conventional and supercritical carbon dioxide (SC--CO(2)) solvents has been examined. The results suggest that locally enhanced solvent density about a solute (solvent/solute clustering) can lead to an enhanced cage effect near the critical pressure in supercritical fluid solvents. This enhanced
    研究了由二枯基酮在常规和超临界二氧化碳 (SC--CO(2)) 溶剂中的光解引起的成对和扩散自由基笼对的行为。结果表明,溶质周围的局部溶剂密度(溶剂/溶质簇)会导致超临界流体溶剂中临界压力附近的笼子效应增强。对于扩散和成对的笼对,这种增强的笼效应在幅度上是相似的。
