Assembly of symmetrical and unsymmetrical platinum(II) rollover complexes with bidentate phosphine ligands / Maidich, L; Zuri, G; Stoccoro, Sergio; Cinellu, Maria Agostina; Zucca, Antonio. - In: DALTON TRANSACTIONS. - ISSN 1477-9226. - 43:39(2014), pp. 14806-14815. [10.1039/C4DT02080D]
Abstract:
The reaction of the cyclometalated rollover complex [Pt(bpy-H)(Me)(DMSO)] (bpy-H = cyclometalated
2,2’-bipyridine) with two diphosphines, dppm (1,1-bis(diphenylphosphino)methane) and dppe (1,2-bis-
(diphenylphosphino)ethane), was investigated. According to the reaction conditions, dppm behaves as a
monodentate, bridging or chelated ligand, whereas dppe gave only chelated species. Some aspects of the
reactivity of the isolated species were studied, including protonation with [H3O·18-crown-6][BF4] and
coordination reactions of mononuclear complexes, obtaining, inter alia, rare examples of unsymmetrical
organometallic species with bridging dppm
