摘要：

The reaction of [PdCl((EN)-N-boolean AND)](n) with AgOAc in methanol afforded the corresponding acetato complexes, [Pd(OAc)((EN)-N-boolean AND)](n) ((EN)-N-boolean AND/n = ECH2CH2NMe2/3; ECH2CH2CH2NMe2/2 (E = S or Se)). The molecular structures of [Pd(OAc)(ECH2CH2NMe2)](3) were established by single crystal X-ray diffraction analyses. The trimeric structures comprise of three palladium atoms bridged through chalcogen atoms of the chelating chalcogenolate ligand forming a twisted six-membered Pd3E3 ring. The acetato-ligand acts in a monodentate fashion. The catalytic activity of [PdCl((EN)-N-boolean AND)](n) and [Pd(OAc)((EN)-N-boolean AND)](n) in Suzuki C-C cross coupling reactions has been investigated. The dimeric acetato complexes showed the best activity in dioxane. (C) 2013 Elsevier B.V. All rights reserved.
