Tris(polymethoxyphenyl)bismuth derivatives: Synthesis and reactivity
摘要:
Tris-(polymethoxyphenyl)bismuth diacetate and dichloride derivatives react with C-nucleophiles in basic medium, as well as with N- and O-nucleophiles under copper catalysis to give good to high yields of the corresponding G, N- and O-arylation products. (c) 2006 Elsevier B.V. All rights reserved.

Na2S2O5 and nitro compounds in a DeepEutecticSolvent (DES) as a reaction medium is described. Thus, triarylbismuthines are used as reagents for the incorporation of SO2 into organic motifs. The bismuth salts formed as by-products can be easily removed from the crude reaction mixture by precipitation with water, while the use of volatile organic compounds (VOCs) as solvents can be avoided in the entire
描述了一种在深度共晶溶剂(DES)中使用铜催化的方法从三芳基双变异蛋白,Na 2 S 2 O 5和硝基化合物开始可持续合成磺酰胺的方法。因此,将三芳基双突变蛋白用作掺入SO 2的试剂变成有机图案。通过用水沉淀,可以很容易地从粗反应混合物中除去作为副产物形成的铋盐,同时在整个过程中可以避免使用挥发性有机化合物(VOC)作为溶剂。用作溶剂的低共熔混合物已得到充分表征,初步结果证明其毒性低。设计的DES还可以进行新颖的多组分反应,从而节省时间并减少纯化步骤,能源和成本。
