An efficient and practical procedure for the aminohalogenation of electron-deficient olefins promoted by hypervalent iodine compounds has been demonstrated. The catalytic efficiency of various hypervalent iodine compounds with different carboxylic and sulfonic ligands has also been investigated and of these (diacetoxyiodo)benzene exhibited the highest activity. A series of substrates, including α,β-unsaturated
已经证明了由高价碘化合物促进的缺电子烯烃的氨基卤化的有效和实用程序。还研究了具有不同羧酸和磺酸配体的各种高价碘化合物的催化效率,其中(二乙酰氧基碘)苯表现出最高的活性。一系列底物,包括 α,β-不饱和酮、肉桂酸酯和肉桂酰胺,在所采用的条件下是可以耐受的,并且以良好的产率和出色的非对映选择性进行氨基氯化/溴化。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 魏因海姆,德国,2008)
