Pd(II) polymeric compounds directed by intermolecular C-H center dot center dot center dot X-C interactions (X = F, Cl): Suzuki-Miyaura cross-coupling catalytic activity by a novel N4-type saturated Pd complex

摘要

New palladium polymeric compounds containing novel tetradentate halogen-substituted 6Me(2)bpX(2-) ligands (6Me(2)bpX(2-) = 1,2-bis(6-methylpyridine-2-carboxamide) halobenzene dianion, X = F for 4, Cl for 5) were constructed by non-classical C-H... X-C interactions, and the novel catalyst 5 was used to carry out Suzuki coupling reactions with aryl iodides and aryl boronic acids under mild conditions. (C) 2006 Elsevier Ltd. All rights reserved.
