Abstract
By using [RuCl2(h4-COD)]n , COD/cycloocta-1,5-diene (C8H12) or [RuCl2(h6-cym)]2, cym/p-methyl-isopropylbenzene, as precursors, N,N-dialkylcarbamato complexes of ruthenium(II) containing the unsaturated hydrocarbon as ligand have been prepared, namely Ru(O2CNiPr2)2(h4-COD), 1; RuCl(O2CNR2)(h6-cym); R/Et, 2; R/ i Pr, 3; Ru(O2CNR2)2(h6-cym), R/Me, 5; R/Et, 6. The crystal and molecular structures of RuCl2(h6-cym)(NHMe2), 4 and Ru(O2CNEt2)2(h6-cym), 6, are reported. Compound 6, which represents the first example of a crystallographically established compound with the h6-arene/O2CNR2 ligand combination, contains both monodentate and bidentate carbamato ligands. The reaction and structural patterns appear to conform systematically to the 18-electron rule for organometallic derivatives.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
