  Direct conversion of methylarenes into dithiocarbamates, thioamides and benzyl esters

  摘要：

  A new strategy for the synthesis of a variety of dithiocarbamates and thioamides has been developed employing inexpensive and readily available methylarenes under metal-free and solvent-free conditions. The approach offers a one-pot procedure and has also been extended to the synthesis of a diverse range of benzyl esters. (C) 2014 Elsevier Ltd. All rights reserved.

  N-Aroylbenzotriazoles have been shown to be efficient reagents for esterification in the absence of organic solvent. Grinding of N-aroylbenzoytiazoles with twofold excess of alcohols for a couple of hours at room temperature gave corresponding esters in high percentage of yields.

  N-芳酰基苯并三唑已被证明是在无机溶剂情况下进行酯化反应的高效试剂。在室温下将N-芳酰基苯并三唑与两倍量的醇磨碎数小时，可以得到相应酯类产物，收率高。
• 5,5′-Dimethyl-3,3′-azoisoxazole as a new heterogeneous azo reagent for esterification of phenols and selective esterification of benzylic alcohols under Mitsunobu conditions

  DOI：10.1039/c004357e

  日期：——

  3′-azoisoxazole is used as a new efficient heterogeneous azo reagent for the highly selective esterification of primary and secondary benzylic alcohols and phenols with aliphatic and aromatic carboxylic acids via Mitsunobu protocols. The reaction is highly selective for primary benzylic alcohols versus secondary ones, aliphatic alcohols and also phenols. The isoxazole hydrazine byproduct can be simply isolated

  5,5'-二甲基-3,3'-偶氮异恶唑通过Mitsunobu协议，它用作新型高效的异质偶氮试剂，用于伯和仲苄醇和酚与脂肪族和芳香族羧酸的高选择性酯化。该反应对伯苄醇与仲醇，脂族醇以及酚的选择性很高。这异恶唑肼 副产物可以简单地通过过滤分离，并循环到其中 偶氮异恶唑 通过氧化。

  日期：——

  Magnetic reduced graphene oxide supported CuO (rGO/Fe3O4–CuO) as a heterogeneous catalyst in cross dehydrogenative coupling (CDC) reactions has been demonstrated for the synthesis of esters using methyl aromatics and aldehydes/benzyl alcohols as coupling partners. Various benzylic esters were prepared efficiently from cheap raw chemicals by employing tert-butyl hydroperoxide (TBHP) as a “green” oxidant

  磁性还原氧化石墨烯负载的 CuO (rGO/Fe 3 O 4 –CuO) 作为交叉脱氢偶联 (CDC) 反应中的非均相催化剂已被证明可用于使用甲基芳烃和醛/苯甲醇作为偶联伙伴来合成酯。通过使用叔丁基过氧化氢 (TBHP) 作为“绿色”氧化剂和四正丁基溴化铵 (TBAB)/四正丁基碘化铵 (TBAI) 作为添加剂，从廉价的原料化学品有效地制备了各种苄酯。由于该催化系统的多相性质，使用简单的过滤来分离催化剂。
