The palladium (Pd) supported on thio-modified multi walled carbon nanotubes (MWCNTs/CC-SH/Pd) was utilized as a useful and reusable nanocatalyst in Suzuki-Miyaura coupling reactions. The catalyst was really efficient for the Suzuki-Miyaura reaction of aryl halides (Ar-l, Ar-Br, Ar-Cl) with phenylboronic acid and conversion was good in most cases. The aryl iodides and aryl bromides reactions take place at room temperature, while reaction of aryl chlorides occurs at temperature of 80 degrees C. The products yields ranged between70% and 96%. The catalyst indicated excellent constancy and could be recycled and reused up to four cycles with no considerable change in its catalytic behavior. (C) 2019 Elsevier Ltd. All rights reserved.
