  Rapid and Ecofriendly Esterification of Alcohols with 2-Acylpyridazinones

  摘要：

  原子经济性的酯化反应在绿色化学中极为重要。在本研究中，我们展示了在无溶剂条件下，通过醇与2-酰基-4,5-二氯哒嗪-3(2H)-酮反应，无需催化剂和添加剂，在$100^{\circ}C$下实现醇的酯化反应。脂肪族和芳香族醇均能以良好至优异的产率转化为相应酯。值得注意的是，该反应无溶剂、原子经济性高、操作简便、反应迅速且成本低廉。

  Herein, we report a ligand-controlled palladium-catalyzed method that enables the synthesis of ynones and γ-butenolides with excellent regioselectivity from the same set of readily available aryl iodides, aryl acetylenes, and BrCF2CO2K. In this reaction, the [PdII]═CF2 does demonstrate electrophilicity and can generate CO readily when reacting with H2O. It is environmentally friendly and safe compared

  在此，我们报道了一种配体控制的钯催化方法，该方法能够从同一组容易获得的芳基碘化物、芳基乙炔和 BrCF 2 CO 2 K 合成具有优异区域选择性的炔酮和 γ-丁烯内酯。在该反应中， [Pd II ]=CF 2确实表现出亲电性，与 H 2 O 反应时很容易生成 CO。与传统方法相比，它对环境友好且安全，并且当前的方案使我们能够以高产率提供炔酮和 γ-丁烯内酯出色的功能容差。此外，利用该策略还可以与相应的酚和醇获得酯。生物活性化合物后期功能化的成功进一步说明了该方案在材料开发和药物发现中的合成效用。
• Catalyst-free esterification of alcohols using 2-acyl-4,5-dichloropyridazinones under microwave conditions

  Efficient and green esterification is of great importance. In this work, we demonstrate the catalyst-free esterification of alcohols by their reaction with 2-acy1-4,5-dichloropyridazin-3(2H)-ones under microwave irradiation. Aliphatic and aromatic alcohols were converted into the corresponding esters in good to excellent yields under microwave irradiation in solvent or solvent-free conditions. It is noteworthy that the reaction is catalyst-free, atom-economic, and rapid and that the process is inexpensive. (C) 2013 Elsevier Ltd. All rights reserved.
