• Electrochemical Formation of Methoxy- and Cyano(phenylazo)alkanes from Aldehyde and Ketone Phenylhydrazones
  作者：Mitsuhiro Okimoto、Yukio Takahashi、Toyoji Kakuchi

  DOI：10.1055/s-2003-41048

  日期：——

  Several aldehyde and ketone phenylhydrazones were electrooxidized in MeOH. Electrooxidation in the presence of KI or tetraethylammonium p-toluenesulfonate as the supporting electrolyte afforded the corresponding methoxy(phenylazo)alkanes. whereas electrooxidation in the presence of KI, NaCN, and HOAc afforded the cyano(phenylazo)alkanes.

  几种醛和酮苯腙在 MeOH 中被电氧化。在 KI 或对甲苯磺酸四乙基铵作为支持电解质的情况下进行电氧化，得到相应的甲氧基（苯偶氮）烷烃。而在 KI、NaCN 和 HOAc 存在下的电氧化得到氰基（苯偶氮）烷烃。

  Three-component heterocyclization of hydrazine with formaldehyde and ethane-1,2-dithiol gave previously unknown 3,3′-bi(1,5,3-dithiazepane). Its stereochemistry was determined by X-ray diffraction. The reaction with higher aliphatic aldehydes RCHO (R = Me, Et, Prn, and Bun) yielded 2,4-dialkyl-3-alkylideneamino-1,5,3-dithiazepanes. The stereochemistry of the latter was determined by 1H and 13C NMR spectroscopy and confirmed by quantum chemical calculations. Heterocyclizations of phenylhydrazine and benzylhydrazine with ethane-1,2-dithiol gave 3-amino-1,5,3-dithiazepanes only with CH2O and MeCHO as the aldehyde component. 3,3′-Bi(1,5,3-dithiazepane) and its N-adduct with MeI were found to exhibit fungicidal activity against microscopic fungi.

  氢化肼与甲醛和乙烯-1,2-二硫醇的三组分杂环化反应生成了之前未知的3,3'-双(1,5,3-二噻唑烷)。其立体化学通过X射线衍射确定。与更高的脂肪醛RCHO（R = 甲基、乙基、丙基和丁基）的反应产生了2,4-二烷基-3-烷基亚氨基-1,5,3-二噻唑烷。后者的立体化学通过1H和13C NMR光谱法确定，并通过量子化学计算进行了确认。与乙烯-1,2-二硫醇的苯基氢肼和苄基氢肼的杂环化只在甲醛和乙醛作为醛组分时产生3-氨基-1,5,3-二噻唑烷。3,3'-双(1,5,3-二噻唑烷)及其与甲基碘的N-加成物显示出对微型真菌的杀菌活性。

  日期：2021.2.5

  A general and practical method for the synthesis of 5-trifluoromethylpyrazoles is reported that occurs by the coupling of hydrazonyl chlorides with environmentally friendly and large-tonnage industrial feedstock 2-bromo-3,3,3-trifluoropropene (BTP). This exclusively regioselective [3 + 2] cycloaddition of nitrile imines and with BTP is catalyst-free and operationally simple and features mild conditions

• Palladium-Catalyzed Synthesis of Aryl Ketones by Coupling of Aryl Bromides with an Acyl Anion Equivalent
  作者：Akihiro Takemiya、John F. Hartwig

  DOI：10.1021/ja064782t

  日期：2006.11.1

  Palladium-catalyzed couplings of aryl bromides with N-tert-butylhydrazones as acyl anion equivalents to form aryl ketones are reported. The coupling process occurs at the C-position of hydrazones to form N-tert-butyl azo compounds. Isomerization of these azo compounds to the corresponding hydrazones, followed by hydrolysis, gave the desired mixed alkyl aryl ketones. The selectivity of C- versus N-arylation

  据报道，钯催化的芳基溴化物与作为酰基阴离子等价物的 N-叔丁基腙形成芳基酮的偶联。偶联过程发生在腙的 C 位以形成 N-叔丁基偶氮化合物。这些偶氮化合物异构化为相应的腙，然后水解，得到所需的混合烷基芳基酮。C-与N-芳基化的选择性受到氮上取代基的强烈影响。N-叔丁基腙发生碳芳基化，而N-芳基腙发生N-芳基化。含有伯和仲烷基以及芳基的腙的芳基化在水解后以良好的产率得到所需的酮。芳环上的官能团，如烷氧基、氰基、三氟甲基、碳烷氧基、氨基甲酰基和酮基，被容忍了。该反应可能通过从含有 eta1-二氮杂烯丙基配体的中间体中形成 CC 键的还原消除而发生。
