Kunz, Peter C.; Thiel, Indre; Noffke, Anna Louisa; Reiss, Guido J.; Mohr, Fabian; Spingler, Bernhard published the artcile< Ruthenium piano-stool complexes bearing imidazole-based PN ligands>, Electric Literature of 36947-69-0, the main research area is crystal structure imidazolylphosphine ruthenium half sandwich preparation catalyst hydration; mol structure imidazolylphosphine ruthenium half sandwich preparation catalyst hydration; imidazole imidazolylphosphine ruthenium preparation phosphorus NMR structure; alkyne hydration catalyst imidazolylphosphine ruthenium half sandwich.
A variety of piano-stool complexes of cyclopentadienyl Ru(II) with imidazole-based PN ligands were synthesized starting from the precursor complexes [CpRu(C10H8)]PF6, [CpRu(NCMe)3]PF6 and [CpRu(PPh3)2Cl]. PN ligands used are imidazol-2-yl, -4-yl and -5-yl phosphines. Depending on the ligand and precursor different types of coordination modes were observed; in the case of polyimidazolyl PN ligands these were κ1P-monodentate, κ2P,N-, κ2N,N- and κ3N,N,N-chelating and μ-κP:κ2N,N-bridging. The solid-state structures of [CpRu(1a)2Cl]·H2O (5·H2O, 1a = imidazol-2-yldiphenylphosphine), [{CpRu(μ-κP:κ2N,N-2b)}2](C6H5PO3H)2(C6H5PO3H2)2 (2b = bis(1-methylimidazol-2-yl)phenylphosphine), a hydrolysis product of the as well determined [{CpRu(μ-κP:κ2N,N-2b)}2](PF6)2·2MeCN (7b·2MeCN), [CpRu(κ1P-3a)(PPh3)]Cl·CH2Cl2 (9·CH2Cl2, 3a = tris(imidazol-2-yl)phosphine) and [CpRu(PPh3)2Cl]·CHCl3 were determined Furthermore, [CpRu(L)2]PF6 (L = imidazol-2-yl or imidazol-4-yl phosphine) were screened for their catalytic activity in the hydration of 1-octyne.
