  Synthesis of arylaminotetrazoles by ZnCl2/AlCl3/silica as an efficient heterogeneous catalyst

  摘要：

  Arylaminotetrazoles were efficiently synthesized from secondary arylcyanamides by application of ZnCl2/AlCl3/silica as a reusable heterogeneous Lewis acid catalyst. 5-Arylamino-1-tetrazoles can be obtained from arylcyanamides carrying electron-withdrawing substituents on the aryl ring, while with electron-releasing groups 1-aryl-5-amino-1-tetrazoles will be produced. The former isomer is also produced within longer reaction times (similar to 20 h) even with electron-releasing groups.

  The newly discovered gold‐catalysed reaction of isocyanides with hydrazoic acid generated in situ from trimethylsilyl azide and methanol (or, alternatively, from NaN3/AcOH) produces either cyanamides or 1‐substituted 1H‐tetrazol‐5‐amines, depending on the amount of available HN3. The reaction proceeds selectively and in generally high yields of either product, thus providing a particularly convenient

  新发现的金催化的异氰化物与由三甲基甲硅烷基叠氮化物和甲醇（或由NaN 3 / AcOH产生）就地生成的氢氰酸反应，可生成氰胺或1取代的1 H-四唑-5-胺，具体取决于可用HN量3。该反应选择性地进行，并且两种产物的收率通常都很高，因此特别方便地获得了广泛的取代1 H-四唑-5-胺，而这些胺否则很难获得。

  method for the synthesis of cyanamides from dithiocarbamate salts via a double desulfurization strategy using molecular iodine is disclosed. Dithiocarbamates, by the action of iodine yield isothiocyanates in situ, which on treatment with aqueous NH3 give thioureas. The thioureas so generated undergo further oxidative desulfurization with I2 giving corresponding cyanamides in good yields. Environmental

  practical process for the direct conversion of nitriles to cyanamides was newly discovered and exhibited a wide substrate scope as well as great functional group-tolerability (36 examples). In this efficient strategy, the in situ generated amidoximes obtained from the reaction of nitriles with hydroxylamine subsequently underwent Tiemann rearrangement, producing the corresponding cyanamides with great

  N-Arylphthalimides can be converted to isoindoles by a two electron reduction and silylation. Cycloaddition with acetylenic dienophiles leads to naphthoquinonemonoimines, which show absorption maxima in the NIR region up to 800 nm.
