Introduction of PdCl2 supported on tartaric acid modified magnetite nanoparticles (Fe3O4@TA-Pd) as a novel catalytic system in Suzuki–Miyaura coupling reaction

Abstract

In this paper, a new magnetically separable catalytic system based on Palladum (Pd) encapsulated with tartaric acid (TA) as a linker (Fe3O4@TA-Pd) is introduced in which TA as a hydroxy organic acid grafted onto the Fe3O4 nanoparticles (Fe3O4 NPs) readily forms complexes with Pd2+. To assess the catalytic capability of the prepared catalyst bearing Pd chelated with TA, it was exploited for achieving some biaryl compounds through Suzuki–Miyaura cross-coupling reaction of aryl halides with phenylboronic acid (PhB(OH)2). This catalyst was reused up to 7 runs with minimizing the change in its activity. Convenient preparation, easy separation and recoverability of this catalyst, facile and efficient transformation to biaryl products along with relatively excellent yields are of the superiorities of this catalyst.
