  Iodine-Mediated Domino Protocol for the Synthesis of Benz­amides from Ethylarenes via sp3 C–H Functionalization

  摘要：

  An efficient, metal-free domino protocol for the synthesis of benzamides has been developed from ethylarenes using aqueous ammonia. The reaction proceeds through the formation of triiodomethyl ketone intermediate in the presence of iodine as the promoter and TBHP as an oxidant followed by nucleophilic substitution with aqueous ammonia, forming an amide. This operationally simple, functional-group-tolerant tandem approach provides an easy access to the broad range of biologically important benzamides.

• A novel oxidative procedure for the synthesis of benzamides from styrenes and amines under metal-free conditions
  作者：Muhammad Sharif、Jin-Long Gong、Peter Langer、Matthias Beller、Xiao-Feng Wu

  DOI：10.1039/c4cc01054j

  日期：——

  An interesting procedure for the oxidative synthesis of amides from styrenes and amines has been developed. Various primary amides were formed in moderate yields (25–81%). Secondary amides can be produced in moderate yields as well (41–68%). Notably, no transition metal catalyst was needed for this transformation. This is the first example of oxidative transformation of styrenes to benzamides.

  开发了一种从苯乙烯和胺进行氧化合成酰胺的有趣方法。在适度的产率（25-81%）下形成各种伯酰胺。仲酰胺也能以适度的产率（41-68%）生成。值得注意的是，这种转化不需要过渡金属催化剂。这是苯乙烯氧化转化为苯甲酰胺的首例。
