  Unexpected Cross-Coupling Reaction between o-Chloroaryl Ketones and Organomanganese Reagents

  摘要：

  Alkyl- and arylmanganese reagents react with o-chloro or o-bromoaryl ketones to give the substituted ketones in high yields. The cross-coupling reaction is performed under mild conditions (-60 to +40 degreesC, 30 min to 4 h) and takes place with excellent chemoselectivity.

  atom efficient ‘trifluoroacetic ester/ketone metathesis’ has been sincerely witnessed. Enolizable alkyl (at least two non-hydrogen atoms) aryl ketones were found to react readily with ethyl trifluoroacetate under the promotion of NaH to afford trifluoroacetic ester/ketone exchange products, trifluoromethyl ketones (TFMKs), and aromatic acid esters, which were quite different from the general Claisen

  真诚地见证了高度选择性和原子效率的“三氟乙酸酯/酮复分解”。发现可烯化的烷基（至少两个非氢原子）芳基酮在NaH的促进下易于与三氟乙酸乙酯反应，得到三氟乙酸酯/酮交换产物，三氟甲基酮（TFMK）和芳族酸酯，它们是完全不同的由一般的克莱森缩合产物1，3-二酮组成。酮与三氟乙酸乙酯之间的反应结果与底物的结构密切相关，由烷基引起的空间拥挤有利于CC键的裂解。DFT研究进一步揭示，复分解反应是动力学上有利的途径。仅使用稍微过量的廉价三氟甲基化试剂，

  Aromatic compounds having an alkyl group with at least 3 carbon atoms are produced in a process comprising at least one of the following steps: (1) a step of contacting a starting material that contains an aromatic compound having a branched alkyl group with at least 3 carbon atoms, with a zeolite-containing catalyst in a liquid phase in the presence of hydrogen therein, thereby changing the position of the carbon atoms of the alkyl group bonding to the aromatic ring of the compound; (2) a step of contacting a starting material that contains an aromatic compound having a branched alkyl group with at least 3 carbon atoms, with a catalyst containing zeolite and containing rhenium and/or silver, in a liquid phase, thereby changing the position of the carbon atoms of the alkyl group bonding to the aromatic ring of the compound; (3) a step of contacting a halogenated aromatic compound having an alkyl group with at least 3 carbon atoms, with an acid-type catalyst, thereby isomerizing the compound; and (4) a step of treating a mixture of isomers of an aromatic compound having an alkyl group with at least 3 carbon atoms, with a zeolite adsorbent that contains at least one exchangable cation selected from alkali metals, alkaline earth metals, lead, thallium and silver, thereby separating a specific isomer from the isomer mixture through adsorption.

  Antihypertensive actions of hydrazidones: study of acylated 2-cholo benzilidenhydrazines. A series of acylated hydrazones: o-Cl-C6H4-C(R1) = N-NH-CO-R, have been prepared and evaluated on spontaneous hypertensive rats (SHR). The more active compounds present a hydroxyl in position-alpha to the acyl group and R1 is a small alkyl group.
