Abstract

Background: Phosphine-free Pd-catalytic platforms, i) combination with chitosan- Schiff base (CS-Py/Pd), ii) immobilized on chitosan-Schiff base (CS-Py@Pd), and iii) anchored to modified carbon nanotube support (CNT@CS-Py@Pd),

Methods: They were evaluated regarding a novel pathway for the cross-coupling reaction of arylboronic acids with acid chlorides.

Results: The CS-Py@Pd platform had the highest catalytic efficiency of the three platforms, yielding moderate to excellent yields of diaryl ketones.

Conclusion: The catalytic activity of the Pd-catalyst was highly dependent upon the manufacturing process and type of support.

Keywords: Phosphine-free Pd-catalyst, Chitosan-Schiff base@Pd, CNT@chitosan-Schiff base@Pd, arylboronic acids, diaryl ketones, coupling reaction.
