Structure of bis-(1,5-cyclooctadiene)-di-μ-(trimethylsilyloxy)dirhodium(I)

Di-μ-methanolato-bis[(η4-tetrafluorobenzobarrelene)rhodium(I)]

“…The second group (zone II) corresponds to geometries formed by crystallographically independent atoms or by atoms related by a twofold rotation axis in [Rh(-OH)(cod)] 2 (Selent & Ramm, 1995) or dibenzocyclotetraene (Singh & Sharp, 2008), in [Rh(-OEt)(cod)] 2 (Ramm & Selent, 1996) or [Rh(-OSiZ)(L)] 2 , with Z = methyl or phenyl groups and L = cod, nbd or carbonyl ligands (Marciniec et al, 1996;Krzyzanowski et al, 1996;Vizi-Orosz et al, 1994). A linear correlation exists between d and (Fig.…”

Multinuclear rhodium complexes supported by tetra- tert -butoxy disiloxide ligand: synthesis, structure, and reactivity

“…25 Siloxide complexes containing a rhodium center have been widely investigated because of their high catalytic activity in reactions such as hydrosilylation and hydroformylation. [27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44] However, most of the rhodium siloxide complexes reported to date are supported by monodentate siloxide ligands. [34][35][36][37][38][39][40][41][42][43][44] To the best of our knowledge, only two examples of rhodium complexes bearing multidentate siloxide ligands, {Rh(COD)} 2 {m-(OSiPh 2 ) 2 O} (COD = cyclooctadiene) and {Rh(CO) 2 } 2 {m-(OSiPh 2 ) 2 O}, have been so far reported.…”
