  使用N杂环卡宾配体调节CH活化反应的多相催化剂的反应性。

  摘要：

  我们报道了在CH活化反应的背景下，添加N-杂环卡宾（NHCs）对异质Ru催化剂的反应性和选择性的巨大影响。我们使用一种简单而稳健的方法，从市售的碳载钌（Ru / C）和不同取代的NHCs开始，制备了一系列新型的空气稳定催化剂。与Ru氘化过程相关的CH氘化过程，可以在很大程度上控制化学结果。实际上，通过启用NHC调节Ru催化剂的反应性：1）提高了有机介质中醇氘化的化学选择性和区域选择性；2）易碎的药学上相关的氘代杂环（嗪，嘌呤）的合成，否则可使用未改性的商业催化剂将其完全还原；

  The non-8-enoate anion undergoes losses of the elements of C3H6, C4H8 and C6H12 on collisional activation. The mechanisms of these processes have been elucidated by a combination of product ion and labelling (2H and 13C) studies, together with a neutralisation reionisation mass spectrometric study. These studies allow the following conclusions to be made. (i) The loss of C3H6 involves cyclisation of the enolate anion of non-8-enoic acid to yield the cyclopentyl carboxylate anion and propene. (ii) The loss of ‘C4H8’ is a charge-remote process (one which proceeds remote from the charged centre) which yields the pent-4-enoate anion, butadiene and dihydrogen. This process co-occurs and competes with complex H scrambling. (iii) The major loss of ‘C6H12’ occurs primarily by a charge-remote process yielding the acrylate anion, hexa-1,5-diene and dihydrogen, but in this case no H scrambling accompanies the process. (iv) It is argued that the major reason why the two charge-remote processes occur in preference to anion-induced losses of but-1-ene and hex-1-ene from the respective 4- and 2-anions is that although these anions are formed, they have alternative and lower energy fragmentation pathways than those involving the losses of but-1-ene and hex-1-ene; viz. the transient 4-anion undergoes facile proton transfer to yield a more stable anion, whereas the 2-(enolate) anion undergoes preferential cyclisation followed by elimination of propene [see (i) above].

  非8-烯酸根阴离子在碰撞激发下会失去C3H6、C4H8和C6H12的元素。通过产物离子和标记（2H和13C）研究以及中和重离子质谱研究，这些过程的机制得到了阐明。这些研究使我们得出以下结论：(i) C3H6的失去涉及非8-烯酸的烯醇阴离子的环化，生成环戊基羧酸根阴离子和丙烯。(ii) C4H8的损失是一个远程电荷过程（远离带电中心进行的过程），生成戊-4-烯酸根阴离子、丁二烯和氢分子。此过程与复杂的氢交换同时发生并相互竞争。(iii) C6H12的主要损失主要通过一个远程电荷过程进行，生成丙烯酸根阴离子、六烯-1,5和氢分子，但在此过程中没有氢交换伴随。(iv) 主要原因是这两个远程电荷过程优先于从相应的4-和2-阴离子中失去丁-1-烯和己-1-烯，尽管这些阴离子已形成，它们具有比失去丁-1-烯和己-1-烯更为替代且低能量的碎片化路径；即暂态的4-阴离子易于进行质子转移以生成更稳定的阴离子，而2-（烯醇）阴离子则更倾向于环化，随后排除丙烯[见上文(i)]。
• On the mechanism of the ethyl elimination from the molecular ion of 6-methoxy-1-hexene

  AbstractIt is shown by 13C and D labelling that the ethyl radical elimination from the molecular ion of 6‐methoxy‐1‐hexene is a very complex process involving at least two different channels. The major channel (80%) is induced by an initial 1,5‐hydrogen shift in the molecular ion from C(5) to C(l) leading via a series of steps to methoxy‐cyclohexnne, which then undergoes a ring contraction to 2‐methyl‐1‐methoxycyclopentane, being the key intermediate for the ethyl loss. The same key intermediate is formed in the other, minor channel (20%) by ring closure directly following an initial 1,6‐hydrogen shift in the molecular ion of 6‐methoxy‐1‐hexene from C(6) to C(l). Collision‐induced dissociation experiments on the [M − ethyl]+ ion from 6‐methoxy‐1‐hexene have further established that it has the unique structure of oxygen methyl cationized 2‐methyIpropen‐2‐al. This ion is also generated by ethyl loss from the molecular ion of 2‐methyl‐1‐methoxycyclopentane itself, as shown by collision‐induced dissociation experiments, thus confirming the key role of the intermediate mentioned.
