  吸附效应对CH 3 CN中苄基衍生物的TiO 2敏化光氧化速率的影响

  摘要：

  在充气和/或脱气的CH 3 CN中，在Ag 2 SO 4的存在下，进行了一系列不同环取代的苄基衍生物（ArCHROR'）在TiO 2敏化的光氧化反应中的竞争动力学实验。根据log k rel vs E p图，假设电子抽象位点的变化是在环上从给电子基团到吸电子基团，从芳族部分到苄基甲基醚的OCH 3基团发生的由于该基团优先吸附在TiO 2上关于芳环。在苄基三甲基硅烷中未观察到该现象，因为由C-Si键和芳族π系统重叠产生的轨道是唯一的吸附位点。α-甲基（在苄醇中）或叔丁基（在苄基叔丁基醚中）的空间位阻会降低吸附程度，但不会影响图的形状，因为OR'应该仍然是首选吸附基团。这也提供了有关悬浮在CH 3 CN中的TiO 2的表面结构的有用信息。版权所有©2003 John Wiley＆Sons，Ltd.

  The specific rates of solvolysis of the benzylmethylphenylsulfonium ion (prepared as the trifluoromethanesulfonate salt) and five benzylic ring-substituted derivatives can be satisfactorily correlated using NT solvent nucleophilicity values. Addition of a secondary term, governed by the aromatic ring parameter (I), shows the sensitivities towards changes in this parameter to fall and those towards

  We report the alkynylation of C(sp2)-H bonds with bromoalkynes (inverse-Sonogashira reaction) directed by synthetically useful ester, ketone, and ether groups under rhodium catalysis. Other less common directing groups such as amine, thioether, sulfoxide, sulfone, phenol ester, and carbamate are also suitable directing groups. Mechanistic studies indicate that the reaction proceeds by a turnover-limiting
