4-溴邻苯二胺的合成

采用两条路线合成４溴邻苯二胺,并对路线（Ⅱ）中水解一步作了探讨这两条路线是：１．用漆原镍催化氢化 ４溴２硝基苯胺;２．邻苯二胺溴化后,碱水解中间体 Ｎ, Ｎ（４溴１,２苯基）双乙酰胺     

New Chiral N,S—Ligands with Thiophenyl at Benzylic Position.Palladium（Ⅱ）—catalyzed Enantioselective Allylic Alkylation

New chiral N,S-ligands with oxazoline and thiophenyl sub-stituents at benzene ring and benzylic postition have been pre-pared and applied in palladium-catalyzed asymmetric allylic alkylation reaction to provide the product with high yield and entantioselectivity (82%-93%)ee.
