  Palladium-Catalyzed Heck-Type Coupling via C–N Cleavage

  摘要：

  A palladium-catalyzed Heck-type coupling method between arenes and ketone Mannich bases via C-N cleavage to synthesize chalcones is reported. This protocol offers good yields and tolerates a broad range of functional groups. Based on the extensive experimental data, we propose a plausible coulping mechanism.

• Pd-Catalyzed C-H Olefination of (Hetero)Arenes by Using Saturated Ketones as an Olefin Source

  Tolerant: By using Pd(OAc)2/PCy3 as a catalyst, both electron‐rich aromatic heterocycles and electron‐deficient fluorobenzenes undergo the dehydrogenative cross‐coupling with (hetero)aryl ethyl ketones in good yields. A broad range of functional groups is tolerated, thus providing a general method for the facile syntheses of chalcones or heterocyclic chalcone analogues. Furthermore, dialkyl ketones can also

  耐受性：通过使用Pd（OAc）2 / PCy 3作为催化剂，富含电子的芳族杂环和缺乏电子的氟苯都可以与（杂）芳基乙基酮进行脱氢交叉偶联，收率很高。宽泛的官能团是可以容忍的，因此提供了一种轻松合成查耳酮或杂环查耳酮类似物的通用方法。此外，二烷基酮也可以参与该转化。
• Studies of substituent effects by carbon-13 NMR spectroscopy. Thiophene and furan chalcone analogues
  作者：Giuseppe Musumarra、Francesco P. Ballistreri

  DOI：10.1002/mrc.1270140512

  日期：1980.11

  Abstract13C NMR spectra of 39 thiophene and furan chalcone analogues in CDCl3 solutions are reported. The effect of substituents on the 13C chemical shifts in the phenyl and in the 5‐membered rings is discussed. 13C NMR shifts are correlated with Hammett parameters and with experimental shifts in the chalcone series.
