Paragraph 0026-0031, (2019/07/16)
The invention discloses a method for synthesizing 1,3-bis(3-aminophenoxy)benzene, and belongs to the field of organic compound synthesis. The method comprises the following steps: carrying out water separation on m-dinitrobenzene used as a raw material in a mixed solvent, adding anhydrous potassium carbonate, dropwise adding a resorcinol solution under the protection of nitrogen to obtain an intermediate 1,3-bis(3-nitrophenoxy)benzene, and hydrogenating the intermediate to obtain the target product 1,3-bis(3-aminophenoxy)benzene. The target product 1,3-bis(3 aminophenoxy)benzene obtained in the invention has a purity of 99% or above, a white to an off-white color and a total yield of 80% or above. Compared with existing synthesis methods, the synthesis method in the invention has the advantages of easy availability of raw materials, no catalyst, low cost, high economical property, and easiness in realizing industrialized production.

Reactions of + PF6- complexes (M = Fe, Ru) with phenoxide nucleophiles were found to proceed with excellent selectivity under mild conditions to give products of monosubstitution.Using aminophenoxides, a preference for O-arylation was observed, while amino alcohols such as prolinol react selectively on nitrogen.Methodology for sequential selective displacement of both chlorides by different nucleophiles is reported.
