  Fragmentation selectivity in electron impact ionization mass spectra of substituted dimethoxybenzenes

  摘要：

  AbstractSeveral 1‐X‐sabstitirted‐3‐methoxy‐4‐trideuteromethoxybenzens were synthesized and their electron impact ionization mass spectra were measured with an ionizing energy of 20 eV. From the peak intensity ratio of [M  CD3 ] and [M  CH3] the fragmentation‐directing ability of the substituent X was evaluated. The most powerful group was found to be NH2, which expelled a methoxy methyl group only from its para position. The CH3 group and four halogen atoms, F, Cl, Br and I, exerted a moderate effect Electron‐withdrawing groups such as NO2, CHO and CN had only a little influence on the fragmentation selectivity. These results were interpreted in terms of the effect of X on the distribution of both the unpaired electron and the positive charge in the molecular ion.

• An efficient one-pot synthesis of 2-aminobenzothiazoles from substituted anilines using benzyltrimethylammonium dichloroiodate and ammonium thiocyanate in DMSO:H2O
  作者：Reuben Dass、Matt A. Peterson

  日期：2021.10

  and ammonium thiocyanate (1.0 equiv) in DMSO:H2O (9:1) at 70 °C gave the corresponding 2-aminobenzothiazoles in excellent isolated yields (75–97%; ave. yield for all substrates = 90%). The reaction worked well for 2(4)-mono-, 2,4-di-, or 3,4,5-tri-substituted anilines, and a wide range of both electron donating groups (MeO, HO, CF3O, Me) and electron withdrawing groups (NO2, CN, CO2Et, CO2H, Cl, F)

  在 DMSO:H 2 O (9:1) 中，在 70 °C 下用苄基三甲基二氯碘酸铵（1.2 当量）和硫氰酸铵（1.0 当量）处理各种取代苯胺，得到相应的 2-氨基苯并噻唑，分离产率高（75-97 %；所有底物的平均产率 = 90%）。该反应适用于 2(4)-单-、2,4-二-或 3,4,5-三-取代的苯胺，以及范围广泛的两种给电子基团（MeO、H2O、CF 3 O、 Me）和吸电子基团（NO 2、CN、CO 2 Et、CO 2 H、Cl、F）耐受性良好。这种方法为其他方法提供了一种有用的替代方法，这些方法要么效率较低（需要 3-7 倍当量的试剂），要么使用剧毒和腐蚀性液体溴2作为氧化剂。
