The N tags were 2,3,4,5,6-pentamethylbenzyl, 3,5-dimethylbenzyl, 4-tert-butylbenzyl and 3-methoxybenzyl groups. The catalytic properties of the complexes were investigated in the Suzuki-Miyaura reactions of aryl bromides with arylboronic acid and in the Heck coupling reactions of aryl bromide with styrene and in the Sonogashira reactions of aryl bromides with phenylacetylene. Generally, dimetallic complexes exhibit good catalytic activities in the Suzuki-Miyaura, Heck, and Sonogashira coupling reactions.eninfo:eu-repo/semantics/closedAccessPalladium N-heterocyclic carbene complexSuzuki couplingSonogashira couplingHeck couplingArticle49510.1016/j.ica.2019.1189692-s2.0-85067609981Q2WOS:000481728800038Q2
