Area of Science:

  • Polymer Chemistry
  • Catalysis
  • Organic Synthesis

Background:

  • Soluble polymer-bound catalysts offer advantages in separation and reusability.
  • Azo dyes can be functionalized and incorporated into catalytic systems.

Purpose of the Study:

  • To incorporate azo benzene derivatives into soluble polymer-bound catalysts.
  • To investigate the use of azo dyes as spectator molecules for catalyst evaluation.
  • To develop an azo dye-ligated polymer-bound palladium catalyst for Heck reactions.

Main Methods:

  • Two strategies for incorporating azo benzene derivatives into polymer-bound catalysts were employed.
  • Catalyst phase preference, concentration, and recoverability were studied using the dye as a spectator.
  • Azo dye-ligated palladium(II) catalysts were synthesized and tested in Heck reactions.
