Synthesis and characterization of organometallic ionic liquids and a heterometallic carbene complex containing the chromium tricarbonyl fragment

Direct reaction between [Cr(CO)6] and arenes with ionic substituents affords the corresponding arene-chromium tricarbonyl complexes, [Cr(CO)3(arene)], in only modest yield. In contrast, these complexes can be prepared in pure form in ...

Neutral metallomacrocycles with four or ten (PEt3)Pd(II) centers

Kay Severin, Rosario Scopelliti, Thomas Brasey

The reaction of (Et3P)PdCl2 with 2,3-dihydroxypyridine, 5-chloro-2,3,-dihydroxypyridine, or 2-hydroxynicotinic acid in the presence of base gives neutral, metallomacrocyclic compounds in which the heterocycles act as dianionic, bridging ligands. The m ...

Syntheses and Structures of the Trinuclear Ruthenium Complexes [RuCl2(PAd2Bu)]3 and [RuCl2(PtBu2Cy)]3

Kay Severin, Rosario Scopelliti, Sébastien Gauthier

The trinuclear Ru complexes [RuCl2(PAd2Bu)]3 (1) and [RuCl2(PtBu2Cy)]3 (2) were obtained by reaction of [(p-cymene)RuCl2]2 with 2 equiv of the resp. sterically demanding phosphine. Crystallog. analyses of 1 and 2 show that the three metal fragments are con ...
