Displacement of dienes from planar complexes. 1. Reaction of (1,5-cyclooctadiene)dichloropalladium(II) with 2,2'-bipyridyl

The preparation and coordination chemistry of phosphorus(iii) derivatives of dialkyl hydrazines

“…[{Pd(C 8 H 12 OCH 3 )(µ-Cl)} 2 ] was prepared using the literature procedure. 26 diethyl ether (20.0 cm 3 ) was added dropwise over a period of 30 min to a stirred solution of 1 M PhMgBr in diethyl ether (2.50 g, 14.0 cm 3 , 13.6 mmol) at 0 ЊC and the reaction mixture stirred for 18 h. Deionized water (20.0 cm 3 ) was added slowly over 10 min and stirring continued for a further 1 h, after which the reaction mixture was transferred to a separatory funnel and the layers separated. The ether layer was dried over MgSO 4 and the drying agent then removed by suction filtration.…”

Five Coordinate Platinum(II) in [Pt(bpy)(cod)(Me)][SbF6]: A Structural and Spectroscopic Study

“…The crystal and molecular structure of a palladium derivative [Pd(Rphen)(cod)(Me)] + (Rphen = 2,9-(4-tBu-C6H4)-1,10-phenanthroline), carrying a quite bulky 1,10-phenanthroline as a diimine ligand, has also been reported [73]. Earlier reports postulated quite similar species [M(N^N)(cod)Cl] + (M = Pt or Pd) as intermediates during reactions of [M(diene)Cl2] complexes with N^N ligands in the presence of nucleophiles (Nu), finally forming complexes [M(en-yl)(N^N)] + in which a nucleophile has been added to one of the diene double bonds, creating a M-C-Nu sigma bond [74][75][76][77][78][79]. Reaction of the four coordinate cod complex [Pt(cod)(Ph)(L)] carrying the hemilabile amino-carboxylate ligand ce-ArCH2NH2CH2C6H4COO − (ce = crown ether) with 2,2'-bipyridine (bpy) produces the structurally-characterized five coordinate complex [Pt(bpy)(cod)(Ph)] + [80].…”
