Synthesis of Diamides and Diimines Derived from 4,4′-(1,3-Phenylenebis(oxy))dianiline, Units for Symmetrical Macrocycles

摘要

4,4′-(1,3-Phenylenebis(oxy))dianiline1is an aromatic diamine compound and has been very less utilized in the organic synthesis. Different diimines and diamides were synthesized by reacting compound1with aromatic and heterocyclic compounds having different functionalities. These longer electron rich spacer molecules were synthesized to utilize them in the near future in making macrocycles of different sizes and functionalities. A hydrazide was also prepared from a diamide spacer molecule containing ester group. A diamide prepared containing nibrobenzene moiety was further reduced to amine to obtain longer spacer diamine molecule than the starting molecule1.
